Ian Somerhalder & Nina Dobrev Get Cozy in the City of Light (PHOTOS)

Have these Vampire Diaries co-stars decided to heat things up off the screen?

Nina Dobrev and Ian Somerhalder were seen taking a leisurely jaunt around Paris on Wednesday afternoon, and it seems the two were getting rather chummy with one another.

So, are they or aren’t they?

While neither have confirmed the relationship, they have been seen spending lots of time together, including attending the White House Correspondent’s dinner together. The two are also very passionate about charity and have worked together to help a number of charitable organizations.

This Paris trip seems to be more about fun though, as both of there moms joined in on the fun. Ian tweeted on May 24:

Just go up, first day in Paris with no work must go play a bit,its healthy:) Thank you for the warm welcome everyone here,its really amazing

The duo were also recently seen in NYC promoting their CW show at the upfronts. Check out some photos of Ian from the event below.
