Lindsay Hubbard and Carl Radke were both ‘very single’

Summer is heating up.

Paige DeSorbo spilled that her “Summer House” co-stars Lindsay Hubbard and Carl Radke were not exclusive on the newest season.

“They were both very single this summer and definitely had other people on their radar than each other,” DeSorbo, 29, told Page Six. “And so when they told all of us that it was romantic, we were like, ‘Oh, OK.’ But everyone was very for it.”

Hubbard finally confirmed her rumored relationship with Radke in an exclusive interview with Page Six on Wednesday.

“We’re definitely dating!” Hubbard, 35, told us, before adding that she and Radke haven’t labeled themselves as “girlfriend/boyfriend” yet.

“We don’t really talk in labels, Carl and I … [But] we’re very much together. We’re very happy.”

DeSorbo gave her stamp of approval on the longtime best-friends-turned-something-more.

“I think they are perfect for each other,” she said. “They’ve always been very close. I mean, they live in the same building, so they hung out every day regardless. So I think it’s really easy to go from, like, being platonic to kind of romantic when you spend that much time with someone … I am very happy for them.”

The fashion guru added that she would “love” to see another “Summer House” wedding.

“I hope that they do make it official and are boyfriend and girlfriend. I know they’re taking their time and just enjoying each other right now. So I hope that they do take the next step because we love couple drama every summer,” she joked.

Radke, 36, and Hubbard’s relationship confirmation comes months after fans speculated that the close friends became something more.

“We’ve always had this thing for each other. Sometimes you’ll look back and be like, ‘Was I just filling the time until I was ready and he was ready?’” Hubbard, 35, said. 

The couple first tried dating during Season 4 of “Summer House,” but it ultimately didn’t work out due to Radke’s past playboy and partying behavior. Radke has since committed to being sober.

“Timing is just an interesting thing. When we tried to date a couple of years ago, we were both in such very different headspaces,” Hubbard told us. “I honestly feel like I tried to cover up my feelings, but I don’t think those feelings ever died.”
