Scheana Marie Shay feuded with her co-stars over the bridal shower

As fans may recall, Shay confronted Schroeder and Doute during last week's episode after discovering Maloney's bridal shower had cost thousands of dollars -- and that she was responsible for paying a percentage of the bill. According to Shay, she shouldn't be held accountable for charges she didn't approve. While she found the idea of spending thousands of dollars on a bridal shower to be ridiculous, Maloney's fun event turned out great and included a number of special guests, including Lisa Vanderpump.

Shay claims she gets mean text messages from Maloney

After Maloney brought up an issue with Shay, claiming she had grown distant during the process of planning her wedding, Shay admitted to feeling upset about Maloney's tendency to send her mean text messages. As she explained, Maloney is a different person when she drinks and she doesn't enjoy her aggressive behavior.

After Shay pointed out her issues with Maloney and her drunken behavior, Maloney quickly fired back at her, suggesting people often say she's fake. "Then why the f**k are you friends with me if I'm fake?!" Shay asks. "Don't be my friend!"
