It’s only been a few weeks, and rapper Lil Wayne is already MAKING WAVES in jail.

We got EXCLUSIVE INFORMATION that rapper Lil Wayne and another inmate got into, what our insider calls a “scuffle.”

According to our ROCK SOLID source, rapper Lil Wayne and another inmate got into a disagreement a few days ago. The insider explained, “I don’t [know] what it [was] about, but neither one was going to let it go and so they handled it.”

What does HANDLE IT mean? Well according to our insider, the inmate CONFRONTED Weezy – and Weezy didn’t BACK DOWN!!! But before any blows were thrown, other inmates broke it up.

And that’s a good look for Weezy. Because according to our snitch, the other dude was WAAAY bigger than Weezy.
