Description:Madonna was treated to a surprise party by her manager to celebrate the success of her new album MDNA. And Madonna managed to treat her manager as well.... with a cake in the face.
While listening to 'B-Day Song' from the LP, she said: "Guy, I wanna give this to you. For real."
She then threw it onto his face and shouted: "That's for making me work so hard motherf**ker!"(0:41)
