Sexy Vampire! See Ian Somerhalder's Hottest Pics

As the actor celebrates his birthday, swoon over steamy pics of the hunky star

Ian Somerhalder went from the runway to the red carpet!

Before rising to stardom as an actor, the hottie modeled for brands such as Versace, Calvin Klein and Guess? Jeans. He transitioned into acting with TV gigs on Smallville and Young Americans, and supporting roles in flicks like Rules of Attraction, before snagging the career-defining roles of Boone Carlyle on Lost in 2004 and Damon Salvatore on The Vampire Diaries in 2009.

From shirtless scenes to humanitarian events, see the hard-bodied hunk's hottest pictures!

Well-Suited

When asked what makes him feel alive by Origin Magazine in April, Ian responded, "It’s one of those things that hits you when you’re not even looking for it. It’s a moment when you find those words surging through your mind -- "I feel so alive right now." There’s varying degrees of it. Acting definitely makes me feel so remarkably alive." The then up-and-coming actor gives the camera a sweet smile at Moveline's 4th annual Young Hollywood Awards in Hollywood on May 5, 2002. Sporting a sharp suit and tie, Ian looks absolutely irresistible!

Baby blues? Check. Sexy smile? Check. Humanitarian? Check! The star heats up the red carpet for the launch of Love Letters To The South, a photography book paying homage to those affected by Hurricane Katrina, in L.A. on Aug. 21, 2006. The do-gooder established the Ian Somerhalder Foundation in 2010 in an effort to inform people on the importance of protecting the environment and animals. "After witnessing the devastation of the oil spill in the Gulf, I knew I had to do something," he told DoSomething.org in 2012. "I drew tremendous inspiration by the outpouring of compassion from others just as grief stricken as myself. I soon realized the immediate need for a platform for these amazing people to come together and have their voices heard."
