Justin Bieber has been banned from singing Boyz II Men's classic hit, 'I'll Make Love To You', by his mother. 

The 17-year-old Canadian hitmaker recently teamed up with the group to record some music for his upcoming Christmas album, and Boyz II Men's Morris revealed that he told them how he has been slapped on the wrist for singing along with the track's rather adult lyrics:

"He told us his mom didn't want him to sing 'I'll Make Love to You,' so he'd sneak and go sing it somewhere. It's also good to know we've influenced such a good artist. It's something that makes us feel we've accomplished something."

Morris also added to MTV News that the group's initial encounter with the 'Baby' superstar was at a hotel in Los Angeles before he was even famous:

"We met him in the hotel, at the Le Montrose, in L.A. and the dude, he had a cast on at the time. And he stepped up and said, 'Oh my God! Boyz II Men, you're my favorite group!' And we're like, 'Oh, OK,' and at the time, we didn't know who he was. He was a new dude, and the next thing you know, he's huge. And I'm like, 'That's the same guy!'"
