New York rapper 50 Cent needs some answers. The hip-hop veteran has singled out longtime friend Floyd Mayweather Jr. for partnering up with R&B singer Teairra Mari for an event.

Fif went to Instagram Saturday (May 26) to get at Mayweather about his loyalty.

Last week, 50 went at Teairra Mari’s attorney Lisa Bloom over their publicized sex tape legal dispute.

A few days ago, both Bloom and 50 traded social media shots at one another.

According to reports, Mari allegedly smashed her ex-boyfriend’s car in North Hollywood, California following the video’s leak.

Teairra’s BF, Akbar Abdul-Ahad, tells us he was working out at his apartment’s gym in North Hollywood Thursday when he got a call from security that a woman was smashing his G-Wagon windows outside. Sure enough … AAA says he came upon Teairra doing just that. We’re told Teairra was using a metal rod from a bar stool, which he claims she was swinging at his passenger side window and windshield. Based on these photos — obtained by TMZ — it looks like someone broke through at least one, and was working on the other. (TMZ)
