'Vanderpump Rules' Tearful Reunion: Emotions Fly When Michael Shay Joins the Cast

Read on for the three biggest OMG moments of the night.

Scheana Marie spent all season saying her husband Michael Shay was “in the studio” at night, but what she knew and didn't admit to her friends was that she knew he was sleeping there “for days at a time.”

When Lisa Vanderpump asked whose money it was Shay was withdrawing in large amounts at a time that Scheana accused him of using on pills, he said, “It was always her money. She always held that over my head. It was never ours. When we got married, it was never our marriage. It was always about you.”

Andy Cohen asked Shay why he didn't communicate how he was feeling.

“She doesn't listen,” Shay said.

“You're never there for me to listen to,” Scheana said through tears.

Lisa threw some “disappointed mom” vibes at Shay, saying Scheana had made her whole world to revolve around him, but Shay defended himself saying he did the same. He also said the money he took was for his business – his music group.

Shay also said he and Scheana grew apart and that he couldn't take her lifestyle anymore.

“She was one way to you guys and she was one way to me,” Shay fired back at everyone defending a distraught Scheana.

When Andy asked Scheana when she felt the relationship began to go south, she said “three months after getting married” because that's when she “found out about the pills.”

Scheana also brought up the “you on top of me” texts Shay admits he exchanged with a girl who was slightly more than a friend.

“It was definitely a connection I didn't have with [Scheana],” he said.

After Shay shamed Scheana for divorcing him on camera, she dropped another on-camera bomb and revealed to Shay that her new boyfriend is Rob Valetta – “You follow him on Instagram,” she said.

“I'll always love you,” Shay said to Scheana. “Coming here was harder than I thought it would be, but I'm glad I did.”

After Jax Taylor's drunk and emotional apology to Stassi Schroeder while on Tom Schwartz and Katie Maloney-Schwartz's joint bachelor/bachelorette party, Brittany Cartwright said she felt some type of way because she wanted the “same kind of emotions.”

“I think since dating Brittany, I've definitely become a better person, and one of the things that I've wanted to do is try to better myself," Jax said. "A lot of water has been under the bridge now, and I feel like we're at a point now where I can sit down and talk and say I'm sorry.”

While in New Orleans, the boys decided to dress in drag, and Kristen Doute decided to provoke an already drunk bunch by bringing up Schwartz's past fling with the Vegas girl. Kristen's boyfriend, Brian Carter, rushed to her defense, and Stassi got to witness the hilarity.

“Everybody f--king grows up, Tom,” Carter, not dressed in drag, said to a drunk and blonde-wig-wearing Sandoval. “And guess what? You grew up to be f--king Sia.”

Stassi could not keep a straight face while reliving the moment.

“I'm in bed and I hear yelling in the hallway, and I go out and I see two guys dressed as women fighting about looking like Sia.”

The comment prompted the whole cheating scandal to resurface. Schwartz continued to say he was not 100 percent sure if he had sex with the girl that night, but he also continued to apologize.
