How do Pink and her motocross racer husband Carey Hart keep things romantic despite their hectic schedules? Text messaging and ... dirt bikes, he tells PEOPLE.

"It's pretty tough because we both travel," Hart, 31, said on Wednesday night at a launch party for Verizon's new Casio G'zOne phone in New York City. "[There is] a lot of text messaging and we call like three or four times a day. We stay very connected."

Hart, who wed Pink, 27, in January 2006 in Costa Rica, recently opened three new tattoo shops and is in the midst of a "comeback year" with his motorcycle racing. His wife is just as busy: She's currently on a 34-city North American tour with Justin Timberlake.

"But no matter what I've got going on I always try to find a week out of the month to go see her," said Hart, which he did to celebrate their first anniversary in January: "We took a nice bath and hung out together and that's about it."

What else do they do to keep their romance alive?

"Random hotels don't hurt," Hart said. "That always keeps it fun. We are kind of boring and kind of wild. Or we'll go camping and get drunk and get rowdy."

Their last trip was to Northern California, where the pair usually "rent motor homes and bring out our dirt bikes and bring the dogs and just ride motorcycles and be full rednecks," Hart said. "It's pretty rad."

At home in Los Angeles, it's skateboarding on their backyard skate ramp, barbequing and hosting friends at their place. "We're very much homebodies," said Hart. "Especially in the whole whack scene of L.A."

Back in New York City, where he was hosting the Verizon event at downtown hot spot One Little West 12th, Hart was hanging out with friends and awaiting the arrival of his wife.

Pink, wearing a sexy black halter dress, made her entrance into the VIP section of the party and asked, "Can I steal my husband for a minute?" Hart stood to embrace his wife and gave her long, romantic kiss, which inspired a round of applause from onlookers.

"They haven't seen each other in a couple weeks," said a pal. "They live the life of rock stars." The couple settled into a corner booth, where they cuddled as they sipped cocktails, setting their glasses down for the occasional kiss.
