What’s His Age Again? Blink-182’s Mark Hoppus (Now 53) Looks Back.

In early March, Mark Hoppus, the singer and bassist for the long-running pop-punk trio Blink-182, and his wife, Skye, were special guests at a Sotheby’s modern and contemporary art auction in London. The sale featured a piece from their collection, a rare Banksy titled “Crude Oil (Vettriano),” up alongside works by Yoshitomo Nara, Gerhard Richter and Vincent van Gogh.

“It was such rarefied air that we’ve never been a part of before,” Hoppus recalled at his home a week later, outfitted in chunky black glasses, a Dinosaur Jr. long-sleeve T-shirt, navy blue Dickies and Gucci Mickey Mouse sneakers. The painting sold for nearly $5.5 million, part of which will go to charity.

It would have been hard to predict such a highfalutin turn for Hoppus back in 1999, when Blink-182 released its magnum opus, “Enema of the State,” which catapulted the band to MTV “Total Request Live” stardom and sold five million copies domestically. The video for the album’s first single, the jocular “What’s My Age Again?,” famously features the band members running unclothed through the streets of Los Angeles. (“Naked dudes are so ridiculous,” Hoppus said. “It just looks comical to me.”) Blink-182 followed up that LP with its first No. 1 album, “Take Off Your Pants and Jacket,” two years later.

Despite Blink-182’s reputation for high jinks, naughty puns and charmingly adolescent hits like “All the Small Things,” Hoppus is remarkably thoughtful in person. Jim Adkins, whose group, Jimmy Eat World, supported Blink-182 and Green Day on a 2002 tour, said in an interview that Hoppus exhibited “human empathy.”

“I know ‘Mark from Blink-182 is emotionally mature’ might seem like an oxymoron if you don’t know him,” Adkins admitted, “but I would say that.”
