50 Cent has been highly critical of rap mogul Diddy as of late, attacking him for aligning himself with 50's rival, Rick Ross, and questioning his artistry. Last night, at BET's post awards show, Diddy fired back, albeit without mentioning any names.

"Yo, let's stop the hate, man. Congratulate!" an enthusiastic Diddy yelled, at the end of the show. "Hate is for suckers. If you hatin', you'se a sucka, and you ashy, and your breath stinks. And you know who I'm talking to, you hatin' a-s crab!"

50 dissed Diddy back in 2006 on a mixtape track called "Hip Hop," implying that Diddy knew who killed his former partner Biggie Smalls, but was too scared to do anything about it. Though they later squashed their beef, it was rekindled apparently, when Diddy began managing Rick Ross.

In recent interviews, 50 has questioned Diddy's relationship with Nicki Minaj and Ross, who the Bad Boy boss controversially compared to Biggie and Lil Kim. Furthermore, 50 said Diddy's "not an artist," and that he's bad for hip-hop.

"His music sucks," 50 said in an interview. "It's bad. He's not an artist anyway, so it doesn't really matter. When you think about it, is he a rapper? Because he says he doesn't write rhymes, he writes checks. Like the same things that I would say are wrong with a Rick Ross project, it's not authenticity to what he's doing. Now he's a singer?...Why does Rick Ross remind him of Biggie? Any Biggie fan objects to that. So how can he say that?"

In a recent performance at the House of Blues in Boston, 50 took it a step further, calling out Diddy and saying, "F--- that n----, tell him I said that s---." We'll be interested to see how this develops, now that Diddy's put together his Dream Team, which includes Ross, Fabolous, Busta Rhymes, DJ Khaled, Nicki Minaj and Red Cafe.
