Sabrina Carpenter Opts to Arrest Margaret Qualley over Jack Antonoff at Final U.S. Short n' Sweet Tour Stop

"This right there ladies and gentlemen, this is a hottie with substance," said Carpenter while singling out Qualley, who starred in 'The Substance'

If you attend a Sabrina Carpenter concert, prepare to get arrested.

At the final North American stop of the 25-year-old singer's Short n' Sweet Tour at the Kia Forum in Los Angeles, she went to "arrest" someone in the crowd for "being too hot" and chose Jack Antonoff — before playfully opting for his wife, Margaret Qualley, instead.

The moment went down before Carpenter played her song "Juno," as she looked around the arena for her "Juno girl" of the evening. Antonoff, 40, appeared on the jumbotron posing with his arms crossed.

"Hey, this is super awkward," said Carpenter from the stage, per a TikTok video. "But I’m sure you’re probably really good at producing. In fact, I’m almost so confident that you could produce someone even hotter than you."

The Bleachers musician, who produced several songs on Carpenter's Short n' Sweet album, then walked out of frame, and Qualley, 30, stepped in with a smile on her face.

"This right there ladies and gentlemen, this is a hottie with substance," exclaimed Carpenter, nodding to Qualley's starring role as Sue in body horror film The Substance.

"Whoever made you, God bless them. God bless their genetics," she added in reference to the film's plot, which sees Demi Moore as Elisabeth Sparkle, a fading star who takes an experimental drug that allows her to live as Sue for brief periods of time and experience fame once again.

Qualley introduced herself to Carpenter, who handed her a set of pink handcuffs and said, "And I think that Margaret and Sabrina are good names to be in a relationship together."

"Oh my God, Margaret, my clothes just fell off thinking about us," she added. "Will you be my Juno girl, Margaret?"

The Kinds of Kindness star, who tied the knot with Antonoff last year after dating since 2021, accepted Carpenter's offer.

Throughout the Short n' Sweet Tour, the "Espresso" singer has arrested celebrities including SNL star Marcello Hernández (as his Domingo character), actress Rachel Sennott, Millie Bobby Brown and more.

The tour's North American leg may be over, but Carpenter will continue in March with shows throughout Europe.

Earlier this month, the "Bed Chem" musician received her first-ever Grammy Award nominations: best new artist, record of the year and best pop solo performance for "Espresso," song of the year for "Please Please Please" as well as album of the year and best pop vocal album for Short n' Sweet.
