Sheree Whitfield's boyfriend isn't talking to her, but he wants a chat with the folks at Bravo ... because he's pissed off about his past appearances on his girl's reality show.
The "Real Housewives of Atlanta" star's BF, Tyrone Gilliams, had his legal team fire off a cease and desist letter to the TV network ... claiming the show's been using his name and likeness without his permission.
According to the legal threat, obtained by TMZ, Tyrone says he never gave the green light for him to become a recurring 'RHOA' storyline back in the day. Even when he wasn't actually on camera, he was often discussed by cast members, and he says the network's been profiting off him without permission.
In the docs, Tyrone is threatening legal action if Bravo doesn't stop using his name and image STAT ... and he's going even further, demanding the network scrub every trace of him from 'RHOA' footage and social media posts, as well as putting the brakes on any marketing or advertising involving him.
Tyrone's been upset lately ... as we first told you, he's not on speaking terms with Sheree because 'RHOA' filming almost put him back in prison due to Sheree's plans to shoot scenes with him at a restaurant. That would've been a huge problem because he's currently sentenced to home confinement.
We reached out to Tyrone's attorney to see if NBC/Bravo's responded to the cease and desist letter ... so far, no word back. Ditto for the network.
