Melissa McCarthy will be hosting SNL this weekend for the 5th time (welcome to the 5 timers club!) and it's been a pretty big year for her as far as live tv comedy is concerned; her guest spots this season as press secretary, Sean Spicer have been almost as popular as Alec Baldwin's Donald Trump impersonation.
But right now it's the transformation that's got people talking in Melissa's latest promo for Saturday's show...enjoy!
BTW: Haim will be the musical guest!
