Vivica A. Fox just got a powerful ally in her ongoing feud with 50 Cent. 
After Fiddy posted a rude meme at his ex's expense yesterday, slamming both her and her guest spot on Empire, the show's star Taraji P. Henson went full-on Cookie Lyon on him and gave the Power star a piece of her mind.

It started with this rude post from 50 on Instagram. “I don’t know why people would want to cross me. I would stay out of my way, if I wasn’t me because I’m gonna keep winning,” 50 Cent wrote. “I think they do it for attention, then they get more attention then they want. I told you POWER was the show to watch. Now Empire lol forget it.”

It's still not clear exactly what set Fiddy off, but Taraji quickly jumped in to his comments to stand up for her friend. “I don’t know about y’all, but I really like to see other people win,” the Emmy nominee writes. “So sad. Use your POWER to unite people and uplift us all. #DoBetter.”

Looks like Vivica appreciated the gesture, adding her own comment to the mix: "Thankx my dawling sis @tarajiphenson I LOVE U TONS! When they go low we go high!"
Sorry, Fiddy. Girl POWER won this round.
