It’s always risky to date a costar- just ask Nina Dobrev and Ian Somerhalder who had to interact with each other at the CW Network’s 2013 Upfront in New York City today (May 16).

The “Vampire Diaries” stars recently split up after a three-year romantic relationship, though they both put on brave faces as they stepped out at The London Hotel.

Nina struck a sexy pose in a bright blue Versace dress with Rupert Sanderson heels while her ex donned some Simon Spurr duds.

Prior to the presser, Somerhalder tweeted, “NY upfronts for Vampire Diaries #5. 5 times a charm right…?”
