Move over, Nina Dobrev! It looks like Ian Somerhalder has a new love in his life … maybe. The 34-year-old “Vampire Diaries” heartthrob was spotted out and about in London with a mystery blonde holding onto his arm. But before Dobrev fans can freak, the girl on his arm appears to be his sister Robyn!

On Wednesday Somerhalder tweeted: “Late night eats with my old man in Soho, sipping Chianti and talking @is_foundation aka Farm plans-priceless…”

That night Somerhalder was photographed leaving London’s Groucho Cub. In a brown leather jacket, jeans and black suede shoes, Somerhalder appeared wary of the photographers while the blonde smiled brightly for the cameras. E! News reports that the girl is believed to be Somerhalder’s sister Robyn, but his rep has yet to confirm. [Click HERE to see the photo of Ian Somerhalder and the mysterious blonde.]

The actor is in London after a brief stay in Paris. He’s currently rehearsing for a new movie, and seemingly using his travels as a way to help him get over his ex, Nina Dobrev. “So. Damn. Happy. Here. In. Europe. :)” he tweeted

Ian Somerhalder’s outing in Soho comes a couple days after Dobrev tweeted up a storm about a friend’s wedding. Like Somerhalder, the “Vampire Diaries” actress found herself on the arm of someone else for the event – her good friend and “Vampire Diaries” executive producer Julie Plec.

Us Weekly broke the news on May 9 that Dobrev and Somerhalder had split after dating for three years. A source told the magazine that they “will continue to work together and remain best friends, which is where the relationship started.”

The couple reunited for the first time post-split at the CW Upfronts. Witnesses report that Somerhalder and Dobrev kept it “professional and seemed to put everything aside to show up and work.”
