What's in a name? Lisa Rinna and Lisa Vanderpump butt heads over what the restaurateur may or may not have said about Kyle Richards on The Real Housewives of Beverly Hills' Tuesday, March 29, episode, as seen in Us Weekly's exclusive sneak peek.

The Bravo series' clip shows the ladies' heated discussion in Dubai, with Rinna claiming to the group that Vanderpump privately said Rinna should have told Yolanda Foster about Richards questioning the severity of Foster's illness.

"Last night, you rewrote history," Rinna, 52, tells Vanderpump, 55. "Why did you come after me at your house and say, 'Bring Kyle into this'?"

The Vanderpump Rules star fires back, "You must have misunderstood me — I did not say that to you."

Watch the tense back-and-forth in the video above.

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