Katy Perry Channels Florence Welch on 'SNL'

Katy Perry channels Florence Welch from Florence and the Machine in “Doggy Duty,” a sketch from this weekend’s episode of Saturday Night Live!

In the sketch, “Doggy Duty” is a film coming out that doesn’t have much of a premise – but it does have a star studded soundtrack!

Also playing celebs in the sketch were Kristen Wiig as Gwen Stefani and Bill Hader as Clint Eastwood.
