HOLLYWOOD, Calif. — Was Drake on the receiving end of one of Lil Wayne's punches?

That's the word coming from an anonymous Young Money member, who tells MediaTakeOut.com that the pair got into a fight last Saturday night, shortly after they performed together at The Joint inside the Hard Rock Hotel in Las Vegas.

So what went down? Well, Lil Wayne was reportedly against flying to Sin City to perform with Drake, but Bryan "Birdman" Williams persuaded him to take the stage with his protégé.

After the show, Lil Wayne allegedly "disciplined" Drake by punching him in the face and then getting escorted away by hotel security. Shortly thereafter, the "Lollipop" singer was reportedly turned away from the concert afterparty at the nearby Wynn.

The insider claims the bad blood stems from Lil Wayne feeling like Drake wasn't there for him while he was locked up at Rikers Island.

Lil Wayne was released from jail on Nov. 4 after serving eight months for gun possession.
