Scheana Marie and her co-stars may be at odds among filming the sixth season of Vanderpump Rules.

While the SUR Restaurant waitress was on good terms with her co-stars at the start of season five while being a bridesmaid for Katie Maloney and Tom Schwartz's wedding, things between her and her co-stars, including Stassi Schroeder and Kristen Doute, took a turn for the worse towards the end of the season.

Since filming came to an end, Scheana Marie has been spending a majority of her time with Ariana Madix and Lala Kent as the other women of the show continue with their super-tight clique.

Scheana was even excluded from a recent cast trip to Europe. With that being said, there doesn't appear to be any love lost and in a series of tweets and she suggested that she is frustrated with her co-stars' behavior.

It all started on Sunday afternoon.

Shortly after Scheana Marie shared the tweet above, fans immediately wanted to know more about who she was talking about.

"Who you subtweeting girl we need answers!" one person wrote.

In response, Scheana Marie cryptically posted three girl emojis but failed to include the names of the three women she was referring to.

In other Scheana Marie news, the reality star may debut a new romance during the sixth season of Vanderpump Rules. While her new man, Robert Parks-Valletta, hasn't yet been seen filming for the show, they have been dating for the past several months, so a guest appearance wouldn't be too surprising. As for Valletta's potential full-time role, the actor appears to be too busy with other gigs to commit to such a thing.

Scheana Marie and her co-stars will return to Bravo later this year for Vanderpump Rules Season 6.
