Halloween Costume Round Up: Celebs Dressed Up As Other Celebs

Ellen DeGeneres as Nicki Minaj

The 50-year old funny lady showed her "oom booms and superbass" as she mimicked Nick Minaj's outfit for a show. Ellen rocked the exact half button cardigan, evealing super boob underneath, as well as loosely fitted leather pants. Topping the outfit off with a blonde wig and pink lipstick, you would think these two were twins! [Photo via]
