There were no signs of trouble in paradise for “Summer House” pair Lindsay Hubbard and Carl Radke — who just announced they’re calling off their engagement — a few days ago in the Hamptons. 

Spies tell us they spotted Hubbard and Radke, along with the rest of the cast, hanging at Montauk hotspot, the Surf Lodge, on Sunday — where hip band, Arizona, was playing.

“They seemed fine,” said a source, who noted the reality TV cast were all partying together.

But another source noted that Hubbard and Radke, “are usually all over each other, and it didn’t look like that on Sunday,” meaning there was none of their usual PDA.

The source also told us, “They were dancing next to each other.”

A different insider tells us that the Bravo cast was hanging out after wrapping filming. 

Four days later, it was revealed that the couple — who were set to wed in just three months — broke up, and that Radke pulled the plug.

“The two were set to get married in November, but Carl told Lindsay he couldn’t move forward with the wedding,” a source told “Entertainment Tonight.”

“The breakup was filmed, and will most likely play out on the next season of ‘Summer House.’”

Page Six has confirmed the split.

Just two weeks ago, Hubbard’s held a garden-themed bridal shower at Cathédrale at the Moxy East Village in NYC — and teased a Bahamian bachelorette party to People that was set to happen in September.

In March, Radke told Bravo host Andy Cohen that they’d already chosen a venue for the wedding.

“We’re locked in… It’s going to be Mexico,” he said.

The duo met in 2016 while filming Season 1 of “Summer House,” and briefly dated during Season 4. They got back together in January 2022.

In August of last year, Radke proposed on a beach in the Hamptons in front of Bravo cameras.

Reps for “Summer House” did not respond to our request for comment.
