R&B singer Teiarra Mari is unfazed by her arch nemesis. The crooner has downplayed disses shot her way by G-Unit boss 50 Cent.

On Friday, Mari went to Instagram to continue promoting her new “I Ain’t Got It” diss record.

Yesterday, 50 hit up Instagram to reveal he flipped Mari’s “Ain’t Got It” catchphrase into his own merchandise.

Earlier in the week, Mari flooded her Instagram page with trolling posts and even pushed her own line of “I Ain’t Got It” merchandise.

Last weekend, the singer released her “I Ain’t Got It” diss record.
