Things are getting heated again between Vivica A. Fox and 50 Cent — and not in a good way.
The actress blasted off on the rapper, her former love, after his appearance on Watch What Happens Live! last night. During the show 50 responded to Viv's allegations that he's gay. But Viv was watching, and she clearly didn't like what she heard.

During the segment, when asked by host Andy Cohen about the Vivica's proclamations, he responded calmly: "Just because I let her lick my ass, she thinks I'm gay." 

The actress wasn't gonna let that slide, however, and came back with the insults on Instagram. She even challenged him to return to WWHL with her and "settle this" face to face:

If that actually happens, we really will be watching. Mean time, see who else 50 has thrown shade at on Wendy Williams, above.
