Ja Rule doesn’t play around. During a recent show at Harrah’s Casino Pool Party in Atlantic City, the Queens, New York, rapper seemed to be having a good time until an unruly fan decided to spoil the mood a little bit.

After the fan threw a beer can on the stage, Ja got furious and demanded to know the identity of the perpetrator. Then, after the audience snitched on the can thrower, Ja Rule ran up and smacked him.

Talk about getting a taste of your own medicine. Watch what transpired below.
