Ian Somerhalder may be taking his role as a vampire on “Vampire Diaries” quite seriously. The 35-year-old actor is reportedly dating Nikki Reed, 26, who played vampire Rosalie Hale in the "Twilight" film series. The two were seen jogging together in California on Sunday, before heading to a farmer’s market together. The two looked quite happy, and appeared to be more than just friends. Somerhalder even rested his chin on Reed's shoulder at one point, and wrapped his arm around her neck as she held on to him.

As "Vampire Diaries" fans know, Somerhalder was the boyfriend of his co-star Nina Dobrev, 25. They dated for three years before splitting in May 2013. Since their split, Dobrev has been linked to a handful of celebrities, such as Derek Hough, Liam Hemsworth, Chris Evans and even another “Vampire Diaries” co-star, Michael Trevino.

Meanwhile, Somerhalder was recently linked to “American Idol” alum Molly Swenson. The pair was allegedly spotted holding hands at an event in April, but Swenson shot down the romance rumors on Twitter.

Reed was previously married to singer-songwriter Paul McDonald, whom she met in March 2011 at a movie premiere. The two collaborated on a song, “All I’ve Ever Needed,” to the soundtrack for “The Twilight Saga: Breaking Dawn Part 2.” But by March 2014, they had announced that they were separating and had been living apart for six months.

They released a joint statement, "After much consideration, Nikki Reed and Paul McDonald are ending their marriage. They have been living separately for the past 6 months due to work obligations. They will continue to share their love of music, and are still working on their debut album 'I'm Not Falling,' releasing 2014. They remain best friends and look forward to their continued journey together."
