Deck the halls with boughs of The Biebs and Boyz, falalalala! Boyz II Men have revealed that the name of their Christmas collab with Justin Bieber is dubbed 'Falalalala,' which is of course a famous lyric/harmony from the holiday standard 'Deck the Halls.'

The song will appear on The Biebs' upcoming holiday album, which will feature original songs. Once The Biebs heard the song, he knew he had to work with the Philadelphia trio on the tune. And Biebz II Men was born!

"He thought we'd be perfect for it," BIIM singer Shawn Stockman told MTV News. "And we went in and locked in."

Boyz II Men's Wanya Morris revealed how the band met The Biebs (before he was the teen sensation he is today). "We met him in the hotel, at the Le Montrose, in LA and the dude, he had a cast on at the time," Morris said. "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."

How quickly things changed! Fast forward a bit and The Biebs was scorching the earth with his heat! Morris recalled, "And the next thing you know, he's huge. And I'm like, 'That's the same guy!'"

The Biebs was raised on a steady diet of Boyz II Men's songs, which were massive in the 1990s. However, their romantic ballad 'I'll Make Love to You' was a no-no for him, courtesy of Ma Bieber.

"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," Morris said. "It's also good to know we've influenced such a good artist. It's something that makes us feel we've accomplished [something and] we're doing our job, [that] a guy so young and so into his craft [is] influenced by three guys from Philadelphia that love to sing."

The collab between The Biebs and the Boyz should be nothing short of pop vocal nirvana.
