Justin Bieber will slip on his Santa hat next month for a command performance for the First Family when he takes the stage for TNT's annual "Christmas in Washington" holiday special.

JB will be joined by Cee Lo Green, Jennifer Hudson, Victoria Justice and the Band Perry on the show, which will be hosted by Conan O'Brien. The special will air on December 16 at 8 p.m. The 30th anniversary program — which will be taped at the National Building Museum in Washington on December 11 — will benefit the Children's National Medical Center. Among the attendees will be President Obama and the First Lady, along with other Washington VIPs, according to a release announcing the show.

While in England to promote the release of his Under the Mistletoe album, Bieber stopped by radio station Kiss FM, where he not only discussed his fans in the White House, but also spilled the beans that he would be performing at the annual show.

"President Obama ... his kids really like me, which is cool," Bieber said. "I'm actually doing 'Christmas in Washington,' and I'm performing for him and the whole Senate and all that."

Bieber previously performed at the event in 2009 — much to the delight of Sasha and Malia Obama — sharing the stage with the likes of Usher, Mary J. Blige and Sugarland. He also took the stage at the White House's annual Easter Egg Roll in 2010, and he's created a kind of bond with the commander-in-chief.

"[Obama] was really nice, and I was just happy to be [at the White House]," Bieber said last year. "We met [Sasha and Malia], took pictures with them, took pictures with the First Lady.

"The first time I met him was a couple months back," he continued. "I got to hang out with him in the Oval Office, which is pretty crazy, because no one really gets to go in there. It was pretty incredible. I got pictures with him."
