Melissa McCarthy has been making us laugh with her impersonations of Sean Spicer [1] on Saturday Night Live [2] all season long, but now she's back . . . as the show's host. Ahead of her episode this weekend, the actress kicked things off by doing two things she does best: impersonating politicians [3] and lip-syncing [4]. As she gets into makeup and costume, she can be seen prancing around the NBC studio as she performs a light-hearted rendition of "I Feel Pretty." Needless to say, we can't wait to see what else she will come up with during her hosting gig.
