Scheana Marie and husband Mike Shay are experiencing marital troubles on Vanderpump Rules, and their co-star, Jax Taylor, isn't sure they'll last.

Lisa Vanderpump Is Concerned Scheana Isn't Taking Mike's Addiction Struggles Seriously

During tonight's episode, Scheana is seen chatting with Lisa Vanderpump about her marriage to Shay.

"I feel like Shay's at this point right now where he really needs to start turning things around," Scheana explains to Vanderpump in a sneak peek at tonight's new episode, shared by Fashion & Style on Saturday. "We're going to go to the gym five times a week [and] we're going to eat better."

'Vanderpump Rules' Star Scheana Marie Claims Mike Shay's Drug Problem Has Been 'Dealt With'

Although Scheana is staying positive, despite their trials, Vanderpump fears she's not taking Shay's addiction seriously.

"Addiction is not cured by some scrambled egg whites," she says.

Then, after Scheana leaves the room and Taylor appears, he and Vanderpump begin to have a discussion of their own regarding their co-stars' marriage.

While Vanderpump encourages Taylor to be supportive of Scheana and Shay, he doesn't think they have much of a chance, claiming, "I have milk with a longer shelf life than that marriage. It's almost like [Scheana's] his mother, not his wife."

During previous episodes, Scheana revealed her husband had been struggling with Vicodin use, taking up to five pills at a time, and said Shay often mixed his pills with alcohol.
