All eyes were on Leighton Meester, gorgeous in a Burberry gown and her Country Strong costar Garret Hedlund.
The two presented at the Golden Globes yesterday and were inseparable all night.
So what went down?
The two attended the party together and were side by side practically the entire evening.
"They were making googly eyes at each other all night, it was adorable," dishes a source at the bash.
"They were hanging out by the bar laughing and talking very close for a long time," continues the fellow partygoer. "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," adds our source. "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."
We would so love if these two were together! They're both equally gorgeous (and super cool, for what it's worth) but as a duo they would be young Hollywood's new power couple.
Garret also talked with Pattinson for a bit.
Wonder if they were sharing stories on Hedlund's On the Road costar and Rob's lady love Kristen Stewart?
One good thing about a possible Meester-Hedlund hookup: if Garrett was snatched up it would ease Twi-hards hearts when he and Kristen start doing lots of promos for their new flick.
You know tabloids are going to concoct some dumb Garrett/Kristen faux-scandal.
We've reached out to Leighton's rep for comment on her possible new beau but have yet to hear back.
Do you approve of the maybe new couple? Sound off below!
