50 Cent was the latest guest on Lil Wayne's Young Money radio.  Fif proved to be quite the chatty patty during the segment, which stretched well over an hour.

Among those 50 discussed was Meek Mill.  Although he didn't say the name, he dropped a pretty obvious sub on the Philly rapper. [Jump to 1:03]

"If you said to me -- I'm not going to say who I'm talking about -- If you represent prison reform, how are signed to a correction officer and you managed by a snitch? Help me with this," 50 wondered. " I just look at certain sh*t and say Wayne, how's that?"

Wayne laughed in response.

The CO is, of course, Fif's longtime rival Rick Ross. 

The snitch is Desiree Perez, Roc Nation's COO.  

Tekashi 6ix9ine and DJ Akademiks have both been on Meek for his business relationship with Perez.  Looks like 50 has been hearing what his former son has been saying.
