Hat's off to you! LeeAnne Locken and Tiffany Hendra do not approve of Brandi Redmond's headwear in The Real Housewives of Dallas' Monday, April 18, episode, as seen in Us Weekly's exclusive sneak peek.

The Bravo freshman series' preview footage shows Locken and Hendra mingling at a glitzy event as they speculate about what is in Redmond's outlandish, homemade hat.

"I'm not really sure what Brandi's wearing," Hendra tells Locken. "I think it has dog poo on it."

Former pageant queen Locken replies, "Really — are you serious? Does it have poop on it?"

Another scene shows the tension between Redmond and Locken — who clashed in last week's series premiere — when the ex–Dallas Cowboys cheerleader walks over to say hi.

"I think the whole purpose of her coming over to say hello to me was to get me to react to this thing on her head," Locken tells the camera. "Why would you wear s--t on your head? [Pantomiming air-kisses] Mwah, mwah, now get the f--k out."

Watch the clip above to see one woman refer to another as the "monster of the sea."

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