Michael Buble 'Duets' With Kanye, Taylor Swift & Gaga on 'SNL': Watch

Not only has Michael Bublé had immense commercial success with his latest "Christmas" album, he's been able to have a little fun with it. As the musical guest on this weekend's (Dec. 17) "Saturday Night Live," Bublé took part in one of the show's trademark mock-ads, this one for a Christmas duets album.

'Christmas' On Track to Be Year's 2nd-Biggest Selling Album


Bublé teamed up with "SNL" cast members to hustle through studio spots with a gun-toting M.I.A., a disheveled Ke$ha, Kanye being Kanye, an in-shock Taylor Swift, plus Gaga, Bieber, Thom Yorke and a host of others. And then there's Russell Brand, who isn't really a rock star, but well, just watch.

The crooner, who's currently dominating the Billboard 200 album chart for three weeks and counting, got down to what he does best: crooning carols. Watch his performances of "Have Yourself A Merry Little Christmas" and "Have A Holly Jolly Christmas" below.

If that's not enough holiday cheer for you, former "SNL" casters Jimmy Fallon (who hosted), Tracey Morgan, Horatio Sanz and Chris Kattan returned to reprise their "Christmas Treat" song. Watch below.
