50 Cent Has a Message for Those Who Would Say His Name For Promo

A good way to get attention is to say 50 Cent's name.

Just last week, Nick Cannon got lots of mentions for calling Fif fat.

NOw 50 Cent has a warning for all those who would say his name.

"If your marketing campaign is say something about 50.  Your not going to make it, have a nice day," 50 typed.

Is this truth?
