Are Brandi and Lisa Locked in a Twitter War?

Brandi Glanville might be the new girl in Beverly Hills, but she's already got the Twitter thing down. "@LisaVanderpump If you dislike me so much PLEASE stop asking me to have a threesome with u Ken!!!! :) luvu darrrrrling," the Real Housewives of Beverly Hills newcomer tweeted at co-star Lisa Vanderpump. "My IQ is sixty! Just ask @LisaVanderpump."

Say what? Before you start choosing whose corner you want to be in, Brandi clarified, "Im always joking!!Clearly @LisaVanderpump has NEVER asked me 2 have a 3some w/ her & Ken! Lighten up people! Lisa knew I was joking!!"

And about that IQ comment? Well, that was in reference to Lisa's jab back at Brandi for calling her 60 on the show. "Obviously she can't count, because I was born in 1960. I think if something's 60, it could be somebody's IQ what do you think of that?" the Beverly-Hills-by-way-of-Britain Housewife tells RumorFix.

Perhaps that's why Lisa's pointing out Brandi's bad grammar? "@BrandiGlanville mmm ...whether...not weather," Vanderfabulous corrected. But the blow-by-blows are all in good fun, Brandi assures us. "@LisaVanderpump has the same sense of humor as I do and we had a laugh about it! Also about my IQ! Ha!" And for good measure, she adds, "I never said she wasn't a beautiful woman! I just honestly thought she was sixty, and trust me she can defend herself!"
