Oh Madonna!, at 50 you should know better. Naughty Naughty Bet you didn't think this pic was going to see the light of day? WRONG!
Madonna is grabbing Model/Kanye's West's girlfriend's tush! Amber Rose liked the pic so much she posed it on Twitter. Look at Kanye's face..... Do you think he approves? Humm.....
This picture was taken earlier this month at the Metropolitan Museum of Art's Costume Institute Ball.
