Master P's birthday isn't for two days but that didn't stop a flash mob from surprising him for that occasion.

Out to lunch yesterday with his son Romeo in Santa Monica, P was not expecting and entertained by a flash mob that formed only feet from him and his team.

In a video surfaced by TMZ, during middle of the flash mob's performance of Psy's "Gangnam Style" the No Limit founder got up and left.

Walking away from the restaurant a woman ran up to Master P and asked him to return for the rest of the performance. She was heard explaining, "Don't leave ... it's your birthday."
