Jennifer Lawrence and Chris Martin were spotted enjoying dinner together at Beverly Hills hot spot La Dolce Vita on Monday night.
"They were super cute together," said an onlooker. "They were laughing a lot and Jennifer was acting all goofy!"
Speculation about a budding romance between Lawrence, 24, and Martin, 37, first surfaced in August, and the two have reportedly been dating since late June.
The Hunger Games actress was first seen with the Coldplay rocker when she attended one of his concerts in London in July.
A rep for Coldplay had no comment.
Lawrence split with longtime boyfriend Nicholas Hoult, 24, over the summer, while Martin separated from wife of 10 years Gwyneth Paltrow, 41, in March.
