Leighton Meester dating Garret Hedlund

Leighton Meester is reportedly dating her 'Country Strong' co-star Garret Hedlund.

The 'Gossip Girl' actress and the hunky actor co-presented an award at the Golden Globes on Sunday night (16.01.11) and sources claim they were inseparable at HBO's after-party at the Beverly Hilton Hotel, where the ceremony had also been held earlier in the evening.

An onlooker told E! Online: "They were making googly eyes at each other all night, it was adorable. They were hanging out by the bar laughing and talking very close for a long time. He had his hand on her back and she was just looking up at him, smiling ear-to-ear as he was leaning down and whispering something to her.

"At one point they turned around and snuck a kiss. But as the night went on they didn't exactly hide their affection for each other. They were all over each other! They seemed really happy."

Leighton recently revealed she thinks being in love is "wonderful" as she enjoys having someone to share her life with.

The 24-year-old beauty said: "It's wonderful to be in love. And it's definitely wonderful to cuddle and have sex and get to experience life with somebody. But it's OK if you don't find him and you're 24. You can find it someday."
