Amber Rose celebrates another year of life today (ugh, breaks my heart that she is going through a divorce in the midst of it!) and last night thought she was going to a regular Halloween party. Turns out, it was a surprise birthday party! Tons of her celebrity friends were in attendance (and in costume) from Chris Brown to Karrueche, Blac Chyna (and her mom…), Nelly, Eva Marcille and more. Amber was a zombie Peggy Bundy, Eva went as Little Red Riding Hood, Karrueche was a bunny, Chris looks like a regular guy wearing a hood LOL, I have NO idea what Blac Chyna is supposed to be but she was definitely showing her a$$…maybe a sexy nun?…and Nelly I think is supposed to be Tupac? I need some of these celebs to try harder at costumes next year! Pics below.
