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.
