Watch Justin Bieber + Drake Duet With Stevie Wonder at ‘House Full of Toys’ Show

Ever since the release of his hotly anticipated 'Mistletoe' album a few weeks ago, it's been looking a lot like Justin Bieber, everywhere you go -- not only did the teenage pop star line up an impressive list of guests for the sessions, he's been performing holiday songs all over the place, from 'X Factor' to Stevie Wonder's annual holiday concert.

Bieber showed up at the latter event over the weekend, where he shared the stage with Wonder and his pal Drake. The trio treated concertgoers to once-in-a-lifetime live renditions of 'Someday at Christmas' and 'Best I Ever Had.'

This year's House Full of Toys show marked Wonder's 16th year of bringing holiday cheer (and presents) to L.A.-area kids from low-income homes. It's traditionally a star-studded affair, with recent special guests including the likes of the Jonas Brothers, Babyface and Janelle Monae -- and the 2011 edition was no different, drawing Michael McDonald and Grammy nominee Gerald Wilson on stage with Bieber and Drake.

"How many people in here are excited?" quipped Bieber after performing 'Someday at Christmas' with Wonder -- and later, Drake gave Beliebers something to be even more excited about: the news that they'll be meeting up in the studio next month to get started on Bieber's next studio album. Merry Christmas and happy new Justin!
