One mirror selfie showed Sweeney, 28, standing beside Braun, 45, as both displayed their costumes.

Their matching comic book looks set the tone for a getaway filled with outdoor activities, sunshine and karaoke.

Carter played the iconic DC Comics superhero in the popular television series from 1975 to 1979.

Sweeney’s costume drew directly from the recognizable Wonder Woman image associated with the actress.

The getaway arrives as Sweeney and Braun continue putting their relationship front and center.

Earlier in the summer, Braun offered another public look at their romance while the two enjoyed a date night in New York City.

Braun filmed the pair riding Citi Bikes through the city after Sweeney revealed that she had never visited Times Square.

He explained the spontaneous nighttime outing in a caption alongside the video.

“When you’re in bed at 11pm and your girl says 'I’ve never been to Times Square….'” he wrote alongside the video.

Braun also filmed Sweeney grabbing food at Shake Shack during their evening together.

The music executive has also spoken openly about his feelings for Sweeney. During an appearance on the “Second Thought” podcast, Braun described the actress in glowing terms while discussing their relationship.

“I've met an extraordinary woman, kind and generous and smart and real and down to earth,” he said.

Braun also called their relationship “one of the biggest surprises ever.”

Sweeney and Braun first generated romance speculation after they were photographed together in 2025.

They appeared at Jeff Bezos and Lauren Sánchez Bezos' wedding in Venice, Italy, and continued making appearances together into 2026.

The couple made their relationship Instagram official May 1 after attending Stagecoach together.

Sweeney shared photos from the event and captioned the post, “cowboy kind of weekend.”

That Stagecoach post served as Sweeney’s public launch of the relationship with Braun.

Their romance began months after Sweeney ended her engagement to film producer Jonathan Davino in March 2025.

Braun was previously married to entrepreneur and activist Yael Cohen.

Their divorce was finalized in 2022, and the former couple share three children.

At the same time, Sweeney has continued her rise in Hollywood after breaking out on HBO’s “Euphoria.”

She also earned critical attention for her work on “The White Lotus.”

Her latest social media carousel brought together the couple’s public romance and their shared superhero theme.

With Sweeney dressed as Wonder Woman and Braun appearing as Superman, the lakeside getaway offered another high profile glimpse of their relationship.
