Summer House’s Lindsay Hubbard, who called off her engagement to Carl Radke in August 2023, accused her ex-fiancé of cheating on her before their split in E! News’ exclusive sneak peek.
Lindsay Hubbard is confronting some overlap in Carl Radke’s dating life.
In E! News’ exclusive sneak peek at Summer House’s April 9 episode, Carl revealed that he was ready to dive back into the world of romance after his split from Lindsay—whose engagement he’d ended the previous summer—and that he had been on a date the week prior.
But despite Carl saying that his first date with an unnamed woman did not go well, Lindsay accused her ex-fiancé of cheating on her with the same girl before their August 2023 split.
“So that was your first date with her,” Lindsay asked her ex, “because it’s come to my attention that you’ve been talking to her since last summer.”
And when Carl insisted that he had only started messaging the woman in the fall after their breakup, Lindsay requested that he “prove it. Show the receipts.” Conveniently, his phone was charging upstairs.
“Your little girlfriend is going around saying that you guys have been messaging since last summer before we were ever broken up,” the 38-year-old continued, while the rest of the cast sat around the table in shock. “’Let me go for a girl who messages me while I’m engaged to be married.’”
“You have a terrible judge of f--king character,” she added, “and now were supposed to feel bad for you that your date went south? You go around acting like a victim, like you haven’t been on any dates. You’ve been talking to this girl since before we broke up.”
Since the pair’s dramatic breakup, Lindsay has moved on to seeing someone new—whose identity she has kept private—and gave birth to their first baby, Gemma Britt Kufe, in early December.
And when it came to sharing her big pregnancy news last July—when the now-airing season nine was filming—she didn’t feel the need to sugar coat it for Carl.
"I'm sure he'll find out when the rest of the world finds out,” Lindsay told People at the time, “but I'm not calling him up and having a conversation with him.”
After all, her focus was on her new relationship and fulfilling her longtime dream of becoming a mother.
“That relationship is in my past,” she explained of her romance with Carl, “and I can't really focus on my past anymore because I'm so focused on my present and my future.”

“To be honest,” she added, “his emotions are no longer my responsibility. It's just not my problem anymore."
Summer House airs Wednesdays at 9 p.m. ET on Bravo. To look back at Lindsay and Carl’s relationship, keep reading.
