Is there an estranged celebrity couple reuniting this year? Last Dec. 30, Coldplay vocalist Chris Martin and "Hunger Games" actress Jennifer Lawerence were spotted eating at a sushi bar.

Refinery 29 obtained a picture showing Lawrence and Martin eating at a sushi bar. According to the source, the picture was taken at Kiwami Sushi in Studio City. In the picture, the two seemed to be chatting.

"They were engulfed in their little world of conversation," a fellow diner tells PEOPLE about the "fun" dinner. "They were into each other and not noticing anyone else around them."

24-year-old actress Lawrence and 37-year-old Martin "seemed to be just content with each other," according to the source.

"He was really listening to what she was saying," the source added.

Meanwhile, Coldplay's vox ex-wife Gwyneth Paltrow opened up about their divorce to Harper's Bazaar U.K.

"We've made a lot of mistakes, and we've had good days and bad days, but I have to say, I'm proud of us for working through so much stuff together - and not blaming and shaming," the 42-year-old "Avengers" actress said.
