Culkin, initially skeptical, was highly impressed by the band's energetic 90-minute performance, praising their stamina and showmanship. The couple, who share two sons, posed with the band and enjoyed the nostalgic concert experience as part of Billie Lourd's birthday celebration. Viral fan videos highlighted the contrast between Song's enthusiastic dancing and Culkin's more reserved demeanor, sparking playful comments referencing their famous roles.
