Nina Dobrev and James Marsden were spotted getting cozy this week.

At a New Orleans bar, Dobrev, 25, and Marsden, 40, were doing more than singing karaoke, notes the Daily Mail. They were at the Cat's Meow on Bourbon Street in New Orleans.

A source said that the duo were "making out in a corner." Marsden rubbed her shoulder when she wasn't singing, and they left the bar in the same cab at about 3 a.m. They continued to kiss.

A source to Hollywood Life that Dobrev is attracted to Marsden.

"Nina thinks James is hot," the source said. "They have met before and they did hook up and had a great time. It was a fun night of drinking and hooking up on Bourbon Street."

This isn't the first Dobrev has been caught with a handsome man at a bar.

Earlier this year she was spotted with "Hunger Games" star Liam Hemsworth in Atlanta. The two were in town shooting, and they were seen together at night.

That date turned out to be nothing, as a source said.

"This is nothing really to get excited about," the source told Hollywood Life. "They both are in Atlanta for filming, which has made things easy for them to get together and hang out. They are definitely very flirty with each other but Liam isn't looking for anything more than hooking up with girls."

Both had come off of long relationships at that time.

Dobrev's relationship has been a hot topic.

She's also been linked to Dominic Howard, who she was spotted with in Monaco. Some believed she was using him to make Ian Somerhalder jealous. And though the two have broken up, they keep in touch and sources believe they will eventually get back together.
