In fan-captured footage of her set on TikTok, Carpenter can be seen singing and dancing to her hit “Espresso” in an orange halter dress and white gogo boots alongside her dancers as the Saltburn star, 31, smiles and claps along as he watches her from the side-stage.

Keoghan — who first sparked dating rumors in December 2023 — recently threw her a birthday party at DUMBO House in Brooklyn on Saturday, May 11 with about 100 friends — including rapper Ice Spice — a source told PEOPLE.
In addition to Big Weekend, the Banshees of Inisherin star has supported the “Nonsense” hitmaker at many of her performances, from her opening set on Taylor Swift’s Eras Tour in Australia earlier this year to flying across the world to cheer her on at Coachella in Palm Springs, Calif., where they also hung out with fellow lovebirds Swift, 34, and her boyfriend, Travis Kelce.
In January, Keoghan and Carpenter stepped out in Los Angeles and went to Luna Luna, an art-centric theme park that recreates the original 1987 art amusement park in Germany.
“It definitely seemed like a date,” an onlooker told PEOPLE of the duo’s outing at the time.
The source added that they were “cute” together and “shared a little kiss.”
