Are Liam Hemsworth
and Nina Dobrev more than just friends?
The Hunger Games
star and Dobrev, star of the CW's The Vampire Diaries
, "definitely looked like a couple" onlooker Danielle Blair tells PEOPLE of their night out together at the Corner Tavern in Atlanta's Edgewood neighborhood during Saturday's early hours.
"Nina was sitting on his lap and they were staring into each other's eyes while talking," adds Blair. "She spent the whole time only talking to him."
The pair remained close late into the night, hanging out near the bar until she left the tavern alone. Hemsworth stayed behind with his male friends until approximately 3 a.m.
Previously, Dobrev, 25, dated her Vampire Diaries costar Ian Somerhalder
for about three years until they broke up in May. Hemsworth, 24, was last linked with Mexican singer-actress Eiza González following his very public split
from former fiancée Miley Cyrus
The actors are both in Atlanta working on separate projects. She is shooting her television series while Hemsworth is filming The Hunger Games: Mockingjay – Part 1
The Corner Tavern is apparently a regular haunt for Hemsworth when he's in town. "I've seen him at least four times [here]," employee Tyler Wallace tells PEOPLE. "He comes in with [costar] Woody Harrelson. Liam is a really nice, laid back guy and a great tipper."
A rep for Dobrev had no comment and a rep for Hemsworth did not respond to a request for comment.
