Love is in the Charleston air.

On this week’s episode ofSouthern Charm,Kathryn Dennisadmits to sleeping with castmateWhitney Sudler-Smithbefore the start of the season.

After murmurs of the possible hookup surfaced during adinner party last week, Dennis finally fesses up to it while talking to her friends at Chelsea Meissner’s housewarming party.

“Our little darling Kathryn and our friend Whitney had a little rendezvous,” saysCameran Eubanksafter Dennis asks the group for the “gossip.”

And Dennis doesn’t deny it.

“I swore to him [I wouldn’t tell]” she says before confirming it happened when they were both in Los Angeles.”

While dating a castmate is not unheard of (see: Meissner and Austen Kroll), this was a particularly shocking revelation given Dennis and Sudler-Smith’s past.

Fans may recall that the two secretly hooked up before Dennis started dating her exThomas Ravenel, with whom she now shares two children. And while they both promised to keep their one-night-stand a secret, Sudler-Smith eventually told Ravenel, leaving Dennis caught in lie.

To make matter worse, Dennis later accused Sudler-Smith, who is also a producer on the show, of being a bad influence on Ravenel while she was pregnant with their daughter Kensie, now 5.

And while Dennis and Sudler-Smith certainly seem to have repaired their friendship, the reality star doesn’t feel bad about spilling the beans.

“Now I don’t give a s—,” she says. “If I was him I’d be like, ‘Yeah man, I sure did. ‘ ”

So how was their night together?

“It wasn’t bad!” says Dennis.

The next day, Kroll and Craig Conover do their best to get Sudler-Smith to open up about the hookup as well, but they don’t succeed.

“F— you,” Sudler-Smith jokes before quickly changing the subject.

Dennis is nowdating country singer Hunter Price. The two have been together since January.
