Chris Brown in Federal Custody, On His Way to D.C. for Trial

Sony Music EntertainmentChris Brown has been taken into custody by U.S. Marshals in Los Angeles, and will be transported to Washington, D.C., where he is set to stand trial on misdemeanor assault charges later this month.

Brown has been in custody at the Los Angeles County jail since March 14, after he was ejected from a facility where he was undergoing court-ordered treatment for anger management and other issues.  That treatment was mandated as part of his probation in his 2009 assault on then-girlfriend Rihanna.

Last October 28, Brown and his bodyguard were arrested in Washington and charged with misdemeanor assault after an incident outside a hotel involving the pair and a third man.  Brown and the bodyguard were accused of hitting the man.

As previously reported, Brown's attorney is seeking to have the assault case dismissed, claiming that prosecutors inappropriately brought the case before a grand jury.  The trial is set to begin April 17.

Brown still faces a probation violation hearing later this month in Los Angeles, stemming from his failure to remain in the court-ordered rehab.

"In honor of may I present the cover of my NEXXXT single, BIRTHDAY," she tweeted.  She then posted a photo of herself as a young girl, sitting at a table in front of a huge, obviously Photoshopped-in birthday cake, with candles that spell "B I R T H D A Y."

Karmin Prepares for New Tour with Bonnie McKee, Talks Debut Album

Epic RecordsThree years after they first signed their record deal, pop duo Karmin are finally out with their debut album, Pulses, in stores now.  The duo will kick off a new batch of tour dates this weekend, with opening act Bonnie McKee, and Karmin's Amy Heidemann says fans can expect "a nice blend" of material during the shows.

"We do, pretty much, the new record, and we have 'Brokenhearted' and 'Hello,'" she tell ABC News Radio, mentioning their two biggest hits.  But her fiance and bandmate Nick Noonan adds that they'll also be including some of the popular YouTube cover songs that first got them attention and led to their record deal, as well as their own versions of current hits.

"We do put some new covers in the middle of new songs, too, so there's some familiarity within the new records," he explains.  Which new songs will they perform? Amy says, "It depends on what we're feeling. It might be Ellie Goulding one night, or Macklemore the other night, so it's fun to throw that into our songs because now, it's like this blend of our originals and covers."

The duo is happy to have Bonnie along for the tour, since they knew her before she was a Grammy-nominated songwriter: that happened this year, thanks to her co-writing Katy Perry's "Roar."

"We had a recording session with her early on and learned her story and she's just a great artist, and we're excited that she was interested in touring with us," Amy tells ABC News Radio. "I think it's going to be fun."  Nick adds that they've known Bonnie since the time they started getting noticed for their YouTube covers, and notes that coincidentally, she actually wrote some of the songs that they covered, such as "Teenage Dream."

As for the new album, Amy says that even though it seems as though it's been in the works for years, it's not as though they haven't released anything at all.

"We came from YouTube, signed a record deal, put out an EP...Hello, and then we recorded this for about a year," she explains. "And we've got 12 songs on it and it's a lot more of Nick singing, it's a duo feel.  It's heavier, there's definitely a lot more emotions: Pulses is about the ups and downs of life, so that's the nutshell."

Still, the album is arriving more than two years since the release of their first big single, "Brokenhearted."  Why did it take so long? "Well, it was amidst touring," Amy tells ABC News Radio. "I guess we did over 600 shows [in] three years...and other things. I mean, life happened!"

"There were definitely a few tracks that were scrapped," Nick adds. "We kind of had the whole thing done, I think once or twice, and then we were like, 'Actually, no' we went back in and got some more songs, and then had to figure out what to do with those songs, so there was kind of a lot of that."  However, the duo says Pulses finally shows off what they call the "Karmin sound."  

The tour kicks off April 6 in Dallas and will wrap May 8 in Salt Lake City.

Could Miley Cyrus, Justin Timberlake Shows in Finland Violate US-Russia Sanctions?

RCA RecordsMiley Cyrus and Justin Timberlake probably didn't expect to wake up this morning and find their names mentioned in the same breath as Russian President Vladimir Putin, but their scheduled concerts at a venue in Helsinki, Finland have dropped them in the middle of the current geopolitical scrum over the Ukraine.

The Financial Times reports that Helsinki's Hartwell Arena, where Justin and Miley are scheduled to perform May 12 and June 1, respectively, is co-owned by three Russians and Putin pals who are subject to current U.S. economic sanctions against Russia, because of the country's annexation of Crimea.  That means U.S. citizens and businesses -- including the singers and their tour promoter, Live Nation -- are forbidden from doing business with the Russian businessmen.  Which means if the concerts go on as planned, both Miley and Justin could find themselves in some seriously hot water.

It seems unlikely, however, that things will get to that point.  Live Nation tells the Financial Times, "We are currently reviewing our portfolio and we will work to ensure the US sanctions against the identified Russians are upheld."

Jeffrey R. Staab/CBSLady Gaga treated David Letterman, Bill Murray, and the CBS late-night host's studio audience to a special performance on Wednesday's edition of Letterman's Late Show.

It all started when Murray told Letterman that one of the items on his bucket list was to meet Gaga. Gaga then popped into the Late Show studio, sporting oversized, yellow-streaked hair, black sunglasses, and a black leather jacket with a black bikini underneath. The trio snapped a selfie.

Gaga then asked Letterman and Murray, “Hey, what are you guys doing tonight, ‘cause I have a show across the street and if you want to come over, I’ll bring you. You can see the performance.  I’ll bring the audience."

Everyone then migrated to the nearby Roseland Ballroom, the legendary New York City venue that will close once Gaga completes her ongoing residency there.

Gaga changed into a red dress for a performance of "Dope," then switched to a white outfit for a live rendition of another ARTPOP track, "G.U.Y." 

Gaga's next Roseland concert is scheduled for Friday.

“American Idol” Recap: The Top Eight Perform Audition Songs

FOXAmerican Idol's top eight revisited their auditions Wednesday night. The contestants reprised the songs that earned them a golden ticket earlier in the season. There was an exception or two: Caleb Johnson, for example, abandoned the original song he performed during his audition.

As usual, Jennifer Lopez, Harry Connick, Jr., and Keith Urban shared their thoughts after each performance.

Here's a rundown of the two-hour show:

Jessica Meuse got things started with her original song, "Blue Eyed Lie." Keith enjoyed the ferocity of her singing, but he wanted her to show more movement with her legs. Harry disagreed with that point, saying that as long as Jessica sings with intensity her leg movement shouldn't matter too much. He did note there was a "dead space" toward the end of the performance. Still, Harry and Keith both felt Jessica did a great job opening the show.

C.J. Harris tackled "Soulshine," by The Allman Brothers Band. J-Lo said C.J.'s gift is touching people with his soulful talent. Harry and Keith both told him it was a big improvement from his audition.

Throughout the night, American Idol offered duets from its contestants that were not judged by the panel. For the first duet, Jena Irene and Alex Preston teamed up on "Just Give Me a Reason," by Pink and fun. singer Nate Ruess.

Sam Woolf played Ed Sheeran's "Lego House" on an acoustic guitar. Harry advised him during future performances to pick one fan in the crowd to focus on and smile at. Keith noticed that Sam's getting looser on stage.

In the second duet of the night, Jessica Meuse and Caleb Johnson sang the Stevie Nicks/Tom Petty tune "Stop Draggin' My Heart Around."

Malaya Watson performed Aretha Franklin's "Ain't No Way." Keith marveled at her control. Jennifer said Malaya's blossoming into a star right before our eyes, and that she will "run away with this competition."

Dexter Roberts again showcased his country vocals with "One Mississippi," by Brett Eldridge. Jennifer gushed that everything the judges have asked Dexter to do, he's done. She also gave a shout-out to Allison Iraheta, the season-eight finalist who provided backing vocals. Harry said it was a perfect song choice, and Dexter sang "the crap out of it."

Sam Woolf and Malaya Watson returned to the stage for a duet of "Lucky," by Jason Mraz and Colbie Caillat.

Jena Irene did a slowed-down version of the Adele hit "Rolling in the Deep." Keith praised her for making the song her own. Jennifer said Jena's mind-set should be to blow all of her rivals out of the water.

Dexter Roberts and C.J. Harris were back to deliver a cover of Darius Rucker's "Alright."

Caleb Johnson took on Aretha Franklin's "Chain Of Fools." Keith loved it, calling Caleb a "rock and roll Viking." Harry thought it was great, too, but he'd be interested in seeing Caleb mix things up and try a performance that's not loud.

Alex Preston closed out the show with an original song, "Fairytales." Harry enjoyed the way Alex shook out "the bravado." The panel seemed to like the arrangement, too.

One finalist will be eliminated on Thursday night's results show, airing at 9 p.m. Eastern time. Daughtry, led by former American Idol contestant Chris Daughtry, will be the musical guest.
