Paul Rudd and Nick Jonas are offering a little musical inspiration for couples planning their big day.While promoting their upcoming musical comedy Power Ballad at the SXSW Conference & Festivals in Austin on March 14, the co-stars opened up about what they consider the “ultimate wedding song.”Jonas, 33, leaned toward a classic romantic choice, naming Bryan Adams’ hit song “(Everything I Do) I Do It for You” as one of his top picks. The singer even gave a brief serenade while discussing the track, highlighting its timeless appeal for couples.The suggestion comes as no surprise, given Jonas’ own romantic history. He married Priyanka Chopra Jonas in 2018 in a lavish, multi-day celebration in India. Their first dance at the Christian ceremony was set to Roberta Flack’s classic “The First Time Ever I Saw Your Face,” a moment guests described as deeply emotional.Rudd, 56, however, took a more unconventional approach. Rather than sticking with traditional love ballads, he suggested couples consider something unexpected.“I don’t know, I kind of like to go against the wedding grain,” he told EW. “I think, like, a great wedding song would be, you know, some kind of punk song or something that is incongruous to what you would think a wedding song would be.”He continued, “I went to a wedding once and I heard ‘Oh Yoko!’ by John Lennon. The couple’s dance, their bride and groom dance, was to ‘Oh Yoko!’ and I thought, ‘That’s great.’ “Paul Rudd tied the knot with Julie Yaeger in a private ceremony in 2003. The couple largely keeps their relationship out of the spotlight, so their wedding song is unknown.Power Ballad debuts in theaters on June 5.
