Update: Brandi Glanville tweeted an apology for her racist remark on the Dec. 9 episode of RHOBH. "I have apologized, I am sorry if I offended anyone especially my friends but I cant type 500000 tweets 2 every single person so enough said," she wrote on Dec. 10.

Previously: Brandi Glanville stepped into it again. On the Monday, Dec. 9 episode of Real Housewives of Beverly Hills, the outspoken reality star, 41, got drunk during a pool party with her bikini-clad castmates, and predictably said something she shouldn't have — and this time, the insult wasn't just ugly, but racist. After newcomer Joyce Giraud admitted that she couldn't swim, Glanville quipped, "You're black." See more pictures of the Housewives here.

Following a stunned silence, LeAnn Rimes' nemesis explained. "It was a joke and my black friends would've laughed crazy, 'cause they don't go in the pool because they will get their weave f*cked up . . .All my black friends can't swim. Is that bad?

Giraud retorted: "Yes, I'm black. What's your problem? Puerto Ricans are black, they're Indian and they're Spanish. So I am a mix of three cultures and I'm very proud to represent all three."

Immediately after that episode's broadcast, Glanville came under fire via Twitter from offended fans. Fellow firebrand Kenya Moore of Real Housewives of Atlanta even chimed in. "Not all black women wear hair weaves, half the women on Beverly Hills Housewives are wearing some fake hair. Brandi could not be more ignorant."

Well aware of her error, Glanville then called in to speak with Andy Cohen on Watch What Happens Live! to explain herself.

"I know what I said was definitely inappropriate, but I say a lot of inappropriate things. I'm not racist, I'm just inappropriate 90 percent of the time! It definitely was not sensitive and I apologize to anyone I offended," the bestselling author said, though she wasn't done defending herself. "But to be honest with you, my friends and I joke with each other this way and they're from all different backgrounds. So I'm sorry and I guess TV's not ready for the real Brandi, but should I censor myself? Is that gonna be exciting?"

Cohen wasn't completely satisfied with that argument, and pressed Glanville further — asking her if she thought the remark was racist.

"I think it was definitely inappropriate," she conceded. "I'm the least racist person of all time. I think the more you defend it, the more you look guilty, so I don't really have to say that much more. I am very sorry with whomever I defended. Defended. Offended!"

Giraud, for her part, has publicly denounced the remark, but a source tells Us Weekly she's actually "happy" that Glanville made the comment. "It elevated her profile," the insider says.
