Are Jennifer Lawrence and Chris Martin giving their relationship another go?

The couple, who split in October after dating for a brief period, were spotted enjoying dinner at Kiwami Sushi in Studio City, Calif., just before the new year.

An onlooker told 'People' magazine, "They were engulfed in their little world of conversation...They were into each other and not noticing anyone else around them."

The cozy meal comes just days after Chris' ex, Gwyneth Paltrow opened up about the duo's separation in 'Harper's Bazaar U.K.
