When it comes to Sabrina Carpenter "arresting" fans at her concerts, no one is safe — not even a Spice Girl.

The "Espresso" singer brought her Short n' Sweet tour to London on Saturday (March 8) where a "spicy" surprise guest make an appearance during the segment where Carpenter "arrests" a concert-goer and gifts them a pair of pink fuzzy handcuffs. According to People, the 25-year-old star placed none other than Emma Bunton, also known as Baby Spice, into "custody" while referencing some lyrics made famous by her iconic girl group.

"You're kind of spicing up my life a little bit... Oh my God, wow. Like really spicing up my life. My clothes are falling off. I'm naked, I'm naked!" she said, as she traded her long sparkling skirt for a shorter look ahead of the next song. While handing the cuffs over, which perfectly matched Bunton's pink shirt, much to Carpenter's delight, the "Please Please Please" singer asked if she would do her the "honors of being mine forever."

Buton isn't the first celebrity taken into "custody" during one of Carpenter's shows. Past famous faces that have been arrested include Jack Antonoff and Margaret Qualley, Marcello Hernandez as his Saturday Night Live character Domingo and Millie Bobby Brown. Last month, the Stranger Things star revealed how she slid into Carpenter's DMs with a "cheeky request" in the hopes of being arrested.
