There is a reason Lil Wayne yelled "Fuck Cash Money" at a concert over the weekend.

And a reason he posed with Birdman's enemies Rick Ross and Trick Daddy last month.

According to TMZ, Baby and Wayne are feuding again.

"Father and son" had reconciled around the New Year, and had spent the last few months discussing ways to settle the $51 million lawsuit Wayne had brought against Cash Money for not paying him and holding up Carter V.

However, TMZ's sources report that Wayne has come to realize that nothing Birdman says is true, and that he can never trust Baby to release Carter V or pay him his money without going to court

So there will be no more talks about settlements.

And Weezy isn't going to be shy about disrespeking Baby in public.
