Katy Perry Does Her Best 'Russell Brand' in 'SNL' Promo: Watch

Katy Perry may have stopped by Studio 8H at Rockefeller Center before as a "Saturday Night Live" musical guest and even done a cameo, but this Saturday (Dec 10), the "Teenage Dream" singer will serve as host. The musical reins will be taken by synthpop star Robyn, who's previously opened for Perry, for the episode.

Here, Perry shows off some of her comedic stylings (and new blonde 'do) with "SNL" cast member Kenan Thompson, and even does an impression of husband Russell Brand. Watch below.

And here's a taste of what to expect, based on her "Bronx Beat" cameo in 2010.

Do you think Katy Perry has the chops to make it through an entire "SNL" episode? Let us know in the comments.
