Hilary Duff paid tribute to her late ex-boyfriend Aaron Carter during a stop on her Lucky Me Tour in Philadelphia on Sunday night, wearing a vintage white T-shirt printed with a photo and the name of the singer, who died in November 2022. The quiet gesture resonated with fans given the pair's shared history as early 2000s teen stars, and comes as Duff continues her first major concert tour in years, keeping alive the memory of a relationship that shaped both their public images.

Duff and Carter were romantically linked from around 2000 to 2003, a period when both were rising Disney Channel and pop music figures; Carter had a hit with "Aaron's Party (Come Get It)," which reached No. 35 on the Billboard Hot 100 in 2000, and appeared on Duff's show Lizzie McGuire in a 2001 episode that ended with an on-screen kiss between the two. Following Carter's death, Duff wrote an emotional Instagram tribute recalling how deeply her "teenage self" had loved him, and earlier this year she described on the Las Culturistas podcast a psychic reading in which Carter's presence unexpectedly came through, calling the experience "wild."
