It's easy to tell that Piers Morgan is fascinated with the longtime beef between Ja Rule and 50 Cent, because he kept asking Ja about it in an interview.

The Murder Inc. rapper was a guest on Piers Morgan Uncensored on Tuesday, and Morgan asked him who would win a fight between him and 50. [Jump to the  16:09-mark]

"That’s happened already too, Piers. You gotta do your research," Ja answered, referring to fighting Fif in Atlanta in the early aughts and hitting him with a tiny wooden bat. 

Ja continued to claim that he won the fight.

From there, he said it's 50 who fuels their beef, not him. 

"It's a one-sided thing," said Ja. "You never see me say anything about him. I just mind my business, do my business … I don’t do the back and forth."

Ja's explanation isn't entirely accurate.  He has a back-and-forth with 50 countless times, most recently last week when Fif clowned him about not being allowed into the UK.

But it would be correct that it's usually 50 who starts the back-and-forths
