Is Sebastian Stan single?

If you like bad boys, then you'll probably like Sebastian Stan. That's not to say the actor is a bad guy in real life - he just plays one on TV. I fell under Stan's spell when he played Carter Bison, the only rich kid in more trouble than Chuck Bass on Gossip Girl . Since then, I’ve followed Stan’s career closely—from his time as the Mad Hatter on Once Upon a Time to his time in Washington, D.C., on the USA Network summer series “Political Animals.” Oh yeah, he also happened to play Bucky Barnes in a little movie called "Captain America." Stan's career is booming, and it couldn't happen to a cuter—well, nicer —guy. It's doubtful that many people could resist Stan's charm, but what was his love life like? More importantly – is Sebastian Stan single?

Sorry to burst your bubble, world - it looks like this guy may have been taken. If you believe the media, Stan has actually had a steady stream of girlfriends in recent years—and they all happen to be the kind of women you love to see on TV. Find out who Stan has dated — and who he's allegedly dating now.

Carter may have dated Serena and Blair on Gossip Girl , but in real life, Stan only has eyes for his co-star Leighton Meester. The couple reportedly began dating in 2008 after meeting on the set of a New York TV series, and Meester called off the relationship after two years together.

Shortly after breaking up with Meester, Stan turned his attention to another television actress, Glee 's Diana Agron. Agron and Stan began dating in May 2011 but broke up in December of that year, reportedly because their long-distance relationship became too challenging.

It looks like Stan and his Once Upon a Time costar have their own fairy tale romance. The couple started dating in the summer of 2012 but broke up about a year later. Fortunately. It looks like we won't be seeing the Mad Hatter return to Storybrooke anytime soon, so there wasn't anything awkward about these two on set.

Margarita Levieva (2014-present)

Stan appears to have found romantic happiness with the former Revenge star. Stan and Levieva met in 2009 while co-starring in the film Spread , but did not start dating until 2014. The actors were recently spotted making out in New York. Wow!
