Outer Banks' Chase Stokes Confirms He's Dating Costar Madelyn Cline

John B and Sarah Cameron are dating in real life!

On Sunday, Outer Banks star Chase Stokes confirmed his romance with costar Madelyn Cline on social media. The actor, 27, shared photos from the couple's beach date on Instagram, along with the caption: "cats outta the bag."

Cline, 22, wrote in the comments section of her boyfriend's post, saying: "Topper punching the air rn" and "I've fallen and I cant get up."

Meanwhile, their costar Jonathan Daviss hilariously said, "Well it's about time."

Stokes and Cline, who play popular couple John B and Sarah Cameron on the Netflix series, first sparked romance rumors in April.

In April, Stokes told PEOPLE he was self-quarantining with Cline and costars Drew Starkey and Rudy Pankow.

"We're all staying together, quarantining together," Stokes said. "We made a huge fort in the living room, so there's this true honesty to the friendship you see onscreen, that is equally present offscreen as well."

Stokes also shared that he and Pankow, who plays his character's best friend, lived together while filming the show.

"We really wanted to make that friendship dynamic real, so we got a place, and every weekend everybody would come over," he said in April of cast members including Cline, Daviss and Madison Bailey.

"We'd play video games, board games, we'd sing, dance, it was a riot. It really felt like an adult version of a YMCA camp, where you're having slumber parties. Even now back in L.A., we're all staying together, quarantining together. There's this true honesty to the friendship you see onscreen that is equally present offscreen as well," he said.
