Exes 50 Cent and Vivica A. Fox certainly don't know how to play nice! After Vivica insinuated that ex boyfriend 50 Cent was gay on last night's Watch What Happens Live!, the rapper is firing back.

The 40-year-old music man, born Curtis Jackson, retaliated with some unflattering pictures of the actress and some harsh words. He also screen grabbed an Instagram that Soulja Boy posted, whom she also implied was gay.

In the sit-down with Andy Cohen, the Empire actress said she thought 50 Cent's criticism of the show for having too much "gay stuff" was, "the pot calling the black." And then she heavily implied he was gay.

Vivica probably should have realized she was about to enter a world of trouble because 50 doesn't seem to let things go. The rapper published a sex tape of his rival Rick Ross' baby mama in order to shame the Maybach Music Group's head honcho. Needless to say -- 50 fights dirty.

We think the whole thing is just tacky and tasteless. Grow up, you two!
