“Summer House” stars Carl Radke and Paige DeSorbo had a fling on Season 3, but Radke insists he is “not jealous” of DeSorbo’s new man.

“I’m not jealous at all,” Radke, 33, told Page Six at this week’s Pink Agenda Gala in New York. “I’m honestly happy for her. She’s awesome. Perry is actually really, really cool. I totally approve.”

Desorbo, 26, revealed she was dating businessman Perry Rahbar after last season wrapped.

“Summer House” co-star Kyle Cooke, who was also present at The Pink Agenda event, joked, “We’re jealous of his brand new G-Wagen, let’s be honest.”

On the upcoming season, Radke said fans will still see him “struggle with the ladies.”

“No spoiler, I’m still single,” he said, adding that he is not dating another Bravolebrity he previously hooked up with: “Vanderpump Rules” star Scheana Marie.

“I went to her birthday in LA [in May],” he said. “She’s a cool chick, [but] long-distance is the wrong distance. We didn’t have sex, but we had a good time, though.”

Although his relationship status hasn’t changed, Radke said work is going much better.

“Professionally I feel like I’m making a good step, so I’m excited about that,” he said. “I’m working with [Kyle’s company] Loverboy. [Kyle] is a friend, mentor, and a boss.”

Cooke, 37, who brought on fiancée Amanda Batula to run the creative side of the low-calorie drink company, said he’s turned his business into a “family affair.”

The friends-turned-colleagues will all return for Season 4 of “Summer House” in 2020, which Cooke said will get “a little dark.”

“At the end of the day, we’re always having fun because we are a group of friends … [but] you put people in a house for 11 weeks, you never know what’s going to happen,” he said. “It was highly eventful.”

Radke added, “It’s intense.”
