Ellen Degeneres Dressed As Nicki Minaj For Halloween, Miley Dressed As Lil Kim, And More Dayum, Ellen. Wicked costume. And now for Miley... if I had that body, I'd probably walk around nearly naked all the time, too. No shame. Kelly Osbourne dressed as Christina Hendricks. Chelsea Hander as a mom-to-be. And Paris Hilton as Miley.
