On Monday, Lee, who joined the series’ sixth season as the first transgender cast member, slammed some of the other ladies for not inviting her to a Girls Night event hosted at SUR Restaurant & Lounge, where most of the show’s stars work.

Lee’s comment was reportedly prompted in response to a Twitter post made by fellow cast member Brittany Cartwright, who tagged multiple female cast mates, including Katie Maloney, Ariana Madix and Scheana Marie, and excluded Lee.

In response to Lee’s tweet, series regular Doute, who previously worked at SUR, shut down any speculation, declaring there was no hate intended.

However, Lee hit back, questioning why Doute was even apart of the conversation since she no longer worked at the restaurant.
