Frito fight! LeeAnne Locken and Cary Deuber butt heads over the cuisine at a party in The Real Housewives of Dallas' Monday, May 23, episode, as seen in Us Weekly's exclusive sneak peek.

In the Bravo series' preview clip, the ladies attend their friends' Gothic State Fair Soirée, where Deuber makes it clear that she won't be joining the others in enjoying the Frito pie.

She also says sarcastically about the chili, "Mmm, got beans in it. Mark will love it if I eat those."

This leads Locken to tell the camera, "Heidi made that chili herself from scratch — and you're going to look down your nose at it?" The former carny kid then tells her friends, "Move over, Gisele — there's a new supermodel in town."

Deuber doesn't appreciate the quip and tells the partygoers about her costar, "Seems like she's being kind of a B."

Watch the tense clip in the video above.

The Real Housewives of Dallas airs on Bravo Mondays at 10 p.m. ET.
