R&B singer Teairra Mari isn’t backing down from the big, bad 50 Cent. The “Love & Hip Hop” star has responded to disses shot her way from the G-Unit boss.

Mari went to Instagram to troll Curtis Jackson with a throwback pic of himself and estranged pal Floyd Mayweather Jr.

Hours prior, 50 jokingly told Mari to hit up Floyd about helping to pay him in a publicized sex tape case.

In late March, Mari returned fire on Curtis Jackson and maintained her stance of not having the money to pay him.

The same week, 50 returned to IG to troll Mari over her not coughing up the big bucks.
