Scheana Marie's marital troubles take center stage on tonight's Vanderpump Rules.

'Vanderpump Rules' Star Scheana Marie Drops 15 Pounds

Following weeks of speculation regarding Mike Shay's drug use, which was noted to be pill-related in the season four trailer, his wife is seen sitting down with her boss and friend, Lisa Vanderpump, to discuss her issues at home.

"It's nothing work related," Scheana explains to Vanderpump in a sneak peek shared by Bravo on Monday. "It has been affecting me at work because people constantly ask, 'Oh, you're married. Let me see your ring. How's your marriage?' And I just, 'Oh it's great,' and I just put on my happy face, and the truth is everything isn't great. It's not perfect, and I keep trying to act like everything is okay. It'll get better if I just keep telling myself, 'It'll be okay and it will get better.'"

"It all just started around Christmas time," Scheana continued. "I noticed his drinking increased a lot... more than drinking. The mixing the pills with alcohol is just a double depressant. You know, it's like, 'Oh my knee is hurting so I'm going to take a Vicodin, but then I'm going to have a couple glasses of wine.'"

When Vanderpump wanted to know how often this was going on, Scheana explained, "It got to the point where it was on a regular basis. He was taking five a day and I had absolutely no idea."
