Melissa McCarthy said that she is "completely obsessed" with the 17-year-old pop star Billie Eilish so naturally Ellen got Billie to scare the crap out of her!
So last month Melissa guest hosted Ellen and redid Billie's video for "Bad Guy" but included her self in it. She's that big of a fan so now that Melissa came back to chat with Ellen Billie jumped out of a box and nearly gave poor Melissa a heart attack!
