Justin’s gotten the chance to perform at the White House in Washington, D.C. twice in his career span already and here – he speaks to MTV.com about the amazing experience. Watch & read all about it below!

“Basically, we went to Washington. We did the thing for the president,” he told MTV News, adding that he called Obama “Mr. President.”

While Bieber is Canadian, he was just as honored as any American would be to perform at the White House. “It was great,” Bieber said. “[Obama] was really cool, really nice, and I was just happy to be there.” As it turned out, Obama’s daughters, Sasha and Malia, really love the 16-year-old pop star. “We met them, took pictures with them, took pictures with the first lady,” Bieber recalled.

While he has it down now, Obama didn’t always know the correct pronunciation of Bieber’s last name. “The first time I met him was a couple months back,” Bieber said. “And when he introduced me, he said, ‘Justin Bye-ber.’ ” Though, Bieber wasn’t really bothered: “Whatever.”

As cool as it is to perform in D.C., Bieber used his celebrity status to do one more thing not many people get a chance to do. “I got to hang out with him in the Oval Office, which is pretty crazy, because no one really gets to go in there,” he said. “But it was pretty incredible. I got pictures with him.”
