Gavin DeGraw leads an interesting life. The singer-songwriter is a contestant on the current season of "Dancing With the Stars," recently shot a video featuring a swimsuit model, and is headlining this year's ShamrockFest with the Dropkick Murphys.

"I don't believe I have, but that should be a lot of fun," DeGraw replied when asked if he's ever shared a bill with the Dropkick Murphys. "I might rock a kilt."

DeGraw may not sport a kilt this weekend, but he has been demonstrating some dance moves recently. The spring season of "Dancing With the Stars" premiered Monday, and DeGraw and his partner, Karina Smirnoff, broke out a foxtrot for a respectable opening night score of 20.

Dancing in front of millions of people exhilarates even the popular DeGraw, who has little dance experience.

"I'm learning a new skill to some degree," said DeGraw the morning after the "DWTS" season premiere, preparing to fly from Los Angeles to Austin, Texas, for a concert. "Even if I turned the foxtrot into the taxidermy version of it, I still enjoyed myself. Why not go out and have a good time? Let's face it, I'm in the entertainment business. It's just another form of entertainment."

DeGraw's video for his new single, "Sweeter," is also a form of entertainment. The video features Sports Illustrated swimsuit model Genevieve Morton in a storyline that has her hooking up with the musician.

"I'm really, really happy with it," DeGraw said. "She's right out of the pages of Sports Illustrated. So we were really excited to have her on the shoot. She really brought something special to the screen. We were all there just kind of having a jaw-dropping experience watching her do her thing. It made the day go by a lot faster and easier than usual."

DeGraw has had a number of hits the last few years, including "I Don't Want to Be" from his 2003 debut, "Chariot."

September saw the release of DeGraw's fourth album, also named "Sweeter." The album features a number of producers and co-writers, in a departure for the artist, who has shown he's not afraid to go out of his comfort zone.

"I consider it much more of a collaboration than a solo album of my own," DeGraw said.
