Feud? What Feud? Lisa Vanderpump Wishes Brandi Glanville 'Happy Birthday'

Lisa Vanderpump called a truce -- at least for today -- with her reality TV enemy, Brandi Glanville, wishing her The Real Housewives of Beverly Hills  costar "happy birthday" on Saturday.

"A birthday should always be a day of positivity," Vanderpump tweeted to Glanville.  "Happy birthday."

As RadarOnline.com has been reporting, the Bravo costars have been at war over comments made about another Housewife, Joanna Krupa.

She's struck back by wearing a T-shirt supporting Glanville's nemesis, LeAnn Rimes.

Glanville hasn't directly responded to Vanderpump's birthday message, but did tweet, "let's stay positive today."

Any guesses on how long it will last?  Tell us in comments.
