Irish boxer Conor McGregor recently struck rapper 50 Cent where it hurts — in his “man boobs.”

Over the past couple of days, McGregor and 50 have traded a handful of jabs. On Monday (March 5), their feud appeared to have been reignited when McGregor turned to Instagram to offer his thoughts on Forbes’ newly-released list of highest paid Hip Hop stars.

The athlete praised JAY-Z and Diddy, but offered this message to 50 Cent: “Someone tag 50cent in this for me. He blocked me on this the mad 50 year old instagram blocker. Ahh don’t block me 50 kid, I still like some of your songs. The older ones hahah.”

Making deals and TAKING deals! Kings recognise Kings! Congrats to @jayz on his number 1 takeover from @diddy in the highest paid Forbes list. What a take-over! Diddy hasn't been number 2 in so long. Until now. Zoom into that two tone with the powder blue on my wrist mate. You might see 1st place again. I am also really interested to see this years Forbes highest paid athletes list. I have now surpassed @cristiano Ronaldo as I told him I would in 2016. Floyd as a retired fighter that makes ZERO substantial revenue outside of them ropes is not on the list, and in the long game, is already dead. Mixed Martial Arts is a glorious game, Floyd. You are going to love it hahaha Someone tag 50cent in this for me. He blocked me on this the mad 50 year old instagram blocker. Ahh don't block me 50 kid, I still like some of your songs. The older ones hahah King bless you all! @burgerking

On the same day, 50 Cent responded with a now-deleted video declaring McGregor is “talented for a white boy.”

“Conor McGregor is a talented fighter and all that,” he said. “He’s talented for a white boy… In order for white people to make a champion, they had to make Rocky.”

The UFC Lightweight Champ didn’t take too kindly to Fif’s critique. On Thursday (March 8), McGregor dedicated an entire Instagram post to slamming the rapper.

“Superior genes my big ballsack mate,” McGregor wrote in the caption. “I am made of granite. You need a bra. You jabbed up fool. Hahahaha you should have stayed quiet and promoted that fight for me on the free like you did. But you just kept going with them fucking memes. Your 50, 50. 50 years old. F*ck off. ”

The latest spat between 50 and McGregor comes nearly one year after McGregor called the rapper a “bitch” during a press conference for his fight with Floyd Mayweather.
