“Little Women: LA” star Matt Grundhoffer admitted he cheated on his wife, Briana Renee, in Wednesday’s episode of the Lifetime series. Last season, he promised Renee he would never cheat on her again, even though he sent sexual messages over social media to dozens of women when she was pregnant with their son. This time, however, the cheating was arguably worse because Grundhoffer became physical with the mystery woman.

Renee, 36, confronted Grundhoffer about the cheating allegations during a cast trip to Alaska. Before that, cast member Terra Jolé told Renee her husband was spotted at the hotel with another woman for hours. He didn’t return to the room he shared with Renee until 5 a.m.

“You shouldn’t be talking to this woman when you’re supposed to be coming up to your room. You totally just said, ‘F--- it!” Renee screamed in the video.

When she asked “what else happened?” he said, “Nothing. Nothing else happened… I didn’t smoke weed.”

He continued: “Nobody else puts up this with much s--- when they’re married to someone.”

In a camera confessional, co-star Jasmine Ortega Sorge detailed how Grundhoffer tried to put the blame on his wife. “Briana keeps questioning Matt. And instead of him calming her down and talking to her like a husband should be he’s turning it around on her, making it her fault, and it’s the sickest thing ever,” Ortega Sorge explained.

During the argument, Grundhoffer tried to shift the blame from himself, once again, by tell the cast of “Little Women: LA” that his wife said nasty things about them. But the girls didn’t buy it and Ortega Sorge bluntly asked if he had sex with the other woman.

“Like why are you twisting the story? She’s asking about something else that happened,” Ortega Sorge said, before asking: “So you didn’t do anything with that woman, at all? Nothing?”

Like Renee, Grundhoffer didn’t respond to the cheating scandal. Instead, he celebrated their son’s birthday. “One year ago today @briana.renee and I were blessed when @maverickjax was brought into this world,” he wrote. “I can't believe how tiny he was! Happy birthday to the happiest, most handsome baby boy in the world! Daddy loves you with all my soul.”
