The story line just took a twist! Lisa Rinna and Lisa Vanderpump got into a heated argument that led to Yolanda Foster walking off the set in part 1 of The Real Housewives of Beverly Hills' season 6 reunion on Tuesday, April 19. But which of the two ladies was in the right?

The shocking battle took place near the end of the episode, with the Melrose Place alum accusing the Sur boss of encouraging her to use the word "Munchausen" to accuse Yolanda Foster of playing up the symptoms of her Lyme disease. Much of this season's drama centered on Rinna suggesting that Foster has been exaggerating the effects of her illness for sympathy, leading to serious tension between the two.

At the reunion, Rinna, 52, brought up her own birthday celebration, mentioning that husband Harry Hamlin encouraged them to support Foster despite her illness. Rinna then told Vanderpump, "You said, 'There goes our f--king story line.'" Vanderpump, 55, denied the claim.

Rinna also said that Vanderpump called her on the phone to tell her to bring up Munchausen syndrome, and when the Vanderpump Rules star replied that she doesn't typically call Rinna, the Harry Loves Lisa star showed printouts of phone records that apparently proved Vanderpump had called Rinna 10 times. As this happened, Foster bolted from the stage and made her way to Andy Cohen's dressing room. In a word: Yowza.

As we all do our best to process everything that has unfolded, it's now time to vote: Do you support Rinna or Vanderpump in the skirmish?

The Real Housewives of Beverly Hills airs on Bravo Tuesdays at 9 p.m. ET.
