Brittany Snow calls it quits with her SMOKING HOT husband

Brittany Snow and husband Tyler Stanaland's marriage has hit the rocks, multiple sources tell PEOPLE.

The Pitch Perfect actress, 36, and Stanaland, 33, are experiencing marriage troubles after he revealed that one of his Selling the OC costars attempted to kiss him off-camera.

A source says the ordeal caused by him being on the show and having their lives turned into a storyline "broke them," adding, "They had issues before, but this is the final straw." Snow "has been trying to find the best time to file for divorce" and maintain their privacy, the source says.

"Brittany never wanted Tyler on the show but he was adamant," the source says. "He wanted to make a name for himself on his own terms."

Another insider says, "They're fully over. All of the girls [on the show] are obsessed with him. He's been trying to be really respectful but it's taken a toll on his marriage 100 percent."

Later on Wednesday, the pair confirmed in joint statements that they are separating: "After time and consideration, Tyler and I have made the difficult decision to separate. This decision was made with love and mutual respect for one another. We have realized we need to take some time and make sure we are each living our most fulfilling and authentic lives. We started this journey as best friends and our relationship will continue to be a priority not only for us but for our dog Charlie. We sincerely appreciate your support and ask for privacy as we navigate this new chapter."

Stanaland previously alleged that his fellow realtor Kayla Cardona has tried to steal a kiss from him on two separate occasions, noting on the Reality Life with Kate Casey podcast that the incidents "didn't happen while we were filming.

"One night, Kayla did try and kiss me. And then it happened another night as well," he said. "And so on the show, out of respect for her, I am just kind of trying to minimize it and brush past it so that there isn't drama. We can all focus on what we should be doing."

"But that was something where I had to kind of set some hard lines and some boundaries and reconsider the social environment a bit. Nothing happened. It was just … something that, you know, you don't do to somebody who is married," Stanaland added.

After she was confronted by fellow agents on the show, Cardona, 33, cleared the air with Stanaland, admitting she "made a huge mistake" and "would have never done that sober." He also apologized for blurring the lines between their professional and personal relationships.

The former pro surfer clarified during his podcast appearance that Snow and their home would not appear on the first season of Netflix's Selling Sunset spin-off.

"As this journey started, I kind of wanted to keep certain parts of my life private," Stanaland explained. "And as time goes on, maybe that'll be different. But for right now, that was kind of the one thing that made me feel safe embarking on such a strange journey."

Snow and Stanaland began dating after they were introduced by mutual friends and announced their engagement in 2019. They tied the knot in March 2020 during an outdoor ceremony in Malibu.
