'Celebrity Apprentice,' Brandi Glanville Sued By 'RHOM' Joanna Krupa! 'RHOBH' Star Said Former 'DWTS' Contestant's 'Pu--y Smelled' On 'Watch What Happens Live!'

Celebrity Apprentice and Real Housewives of Beverly Hills star Brandi Glanville is being sued by Real Housewives of Miami star Joanna Krupa after saying disparaging things about her on national television.

According to Life & Style, Joanna's lawyer sent Eddie Cibrian's ex-wife a letter saying she will be sued for "slander, libel, defamation and/or intentional infliction of emotional distress."

In a shocking appearance on Bravo's Watch What Happens Live, the mother-of-two told host Andy Cohen that Joanna slept with RHOBH co-star Yolanda Foster's ex-husband Mohamed Hadid and that he said Joanna's "pu--y smelled." This caused fellow WWHL guest Mark Consuelos to fall on the floor.

"She doesn't even know me!" the former Dancing with the Stars contestant told the mag.

In the letter to Brandi, Joanna's lawyer also claims that LeAnn Rimes's rival insinuated that Joanna committed adultery by sleeping with Mohamed while he was married to Yolanda.

"[Brandi's comments] have humiliated and harmed Joanna," a source told Life & Style. "Joanna hired heavyweight lawyer Ray Rafool to sue because enough is enough."

As MStars News reported, Brandi isn't new to feuding with a fellow "Real Housewife." In this season's Celebrity Apprentice, Brandi has had a very public battle on and off camera with Real Housewives of Atlanta star Kenya Moore.

In an interview with thewrap.com, Kenya said, "I think Brandi's sole reason for joining the show was to be an irritant toward me."

Brandi then fired back to E! News, saying, "Two Housewives, there can only be one, so you have to choose: It's either super-evil Kenya or trash-mouth Brandi — pick! But I'm not evil, that's the thing, there's pure evil there."

"[Brandi] was confused," NeNe Leakes's nemesis shot back. "She was drunk and looking in the mirror and that's what came out."

The former Miss USA continued the daggers when talking to Us Weekly: "She's out of her league here, particularly with me. She doesn't want to fight with me. I mean, if it were a bar setting, I think she would do OK. If it were a drinking competition, OK. But this is not that."

Do you think Joanna has a right to sue Brandi over what she said on Watch What Happens Live?
