Michael Buble was the musical guest on this weekend's episode of 'Saturday Night Live' (Dec. 17) and the crooner let audiences know that his 'Christmas' album is such a best seller that it demands a repeat in the form of 'Christmas Duets.' That follow up would feature Buble performing the festive holiday classics with the likes of Taylor Swift, Justin Bieber, Kesha and more.

In the hilarious clip, the even-keel Buble performs against Kristen Wiig as Taylor Swift, complete with curly cues, guitar and that shocked and confused look on her face. Episode host Jimmy Fallon stepped into Bieber's pumped up kicks and purple hoodie. With the side-swept bangs, Fallon was doppelganger for the Biebs with his dancing, winking and making of the heart shape with his hands. Buble tells him to take it down a notch.

Kesha joined Buble for a rendition of '12 Days of Christmas,' only she swaps out lyrics to sing "seven days of puking." Also, Scotty McCreery was parodied, with his uber deep voice proving too much for even someone as classy and charming as Buble to handle.

The most outrageous duet partners were Lady Gaga, who was simply reincarnated as a Christmas tree, and Kanye West, who jacks the spotlight from Buble while auto-tuning "I'm so much better than you" about Jesus.
