50 Cent has waded into the McGregor-Mayweather farce after being a labeled a "bitch" by the Irishman.

Posting on Instagram, the rapper shared a video of the incident followed by the caption: "What the fuck wrong wit this white boy, you fighting Floyd not me fool. LOL."

He then followed up the video with a post about his new TV show, Power, along with an image of McGregor tapping out in his fight against Nate Diaz. "Little leprechaun Vs. KANAN July 16 Sunday 9Pm POWER Episode 4. Ain't no tapping out over here LOL," read the caption.

Prior to McGregor's comments, made at last night's New York press conference, 50 had appeared on Jimmy Kimmel Live! to talk about the fight and promote his show. While he admitted he'd be supporting "little brother" Mayweather, 50 was complimentary of McGregor, saying he thought the MMA champion at least stood a chance. All that changed, of course, when word got back about the "bitch" slur. Watch the video at the top of the page.

Mayweather and 50's relationship is rumored to have disintegrated in recent years, but the rapper confirmed he would be ringside for the fight.

Mayweather and McGregor hold a final press conference in London tonight. Here's a look back at what went down in Toronto.
