Justin opened up to Billy Bush on Access Hollywood on why it's so important to keep his childhood friends close.

“I don’t really let anyone in my circle. I don’t really trust a lot of people, which is sad," he said. "But I kind of keep the people I grew up with close to me.”

He also talked about one of the most catchy and different songs on the highly anticipated Christmas album, which is his version of "Drummer Boy" featuring Busta Rhymes.

“We have talked about doing a collaboration for a while," Justin explained. "Him and Scooter actually know each other back in Atlanta, they did some stuff. I’ve loved Busta for a long time.”

“I asked him at an awards show, I was like, 'yo, we have to do something together.' He was like 'yea, we got to make something happen.' ”

And so, they did!

“For the Christmas album I was doing, like, this rap on 'Drummer Boy,' I was like 'yo lets get Busta on this, so we contacted him and he was, like, down.' ”
