Justin Bieber is bridging the generation gap with his star-studded holiday album, Under the Mistletoe. He's collaborated with a string of stars like Mariah Carey, Busta Rhymes and Usher for the November 1 LP. But it's the Biebs' pairing with Boyz II Men that's sure to expand the teen star's fanbase.

We spoke to BIIM's Nate Morris via Skype during our special "MTV First: Justin Bieber" this week, and he shared his thoughts on the young singer as well as their holiday collabo "Falalalala."

"We respect him, man," the R&B crooner told MTV News' James Montgomery. "I watch what he does, I watch what the people around him do, and they're guiding him in the right directions. You don't hear anything bad about this guy. He has his head on straight."

JB's team includes his mother, Pattie, who Morris said clearly has Bieber's best interests at heart. "His mom has got his focus in the right direction and as long as she does that, he'll be just fine," he added.

So will Boyz II Men head to the studio again with the pop superstar? Morris was optimistic, saying, "Oh, without a doubt. We just have to figure out the right circumstance. This was perfect for us because, you know, we wanted to try to make sure that the first song we did together was something that people could accept the two artists doing together. ... If there's a soundtrack or whatever that comes along that we can create something special, that'll be hot."

BIIM's team-up with JB is just one of many treats the group has planned for their comeback. On October 25, they're set to drop Twenty, a new double-disc set that features both brand-new tracks and re-recorded classics.

"It's a collection of our best work, we think," Morris admitted. "I mean, 20 years is a long time to be in this business, so we tried to encompass a little bit of everything. ...We wanted to bring everything together all on one [album] even for those young Bieber fans who may not know all the Boyz II Men records — they can get all the history and today's music on one CD."
