The on-again off-again romance between actress Jennifer Lawrence and Coldplay frontman Chris Martin reportedly is on again.

People magazine said Thursday that "Silver Linings Playbook" Oscar-winner Lawrence, 24, and Martin, 37, were seen having dinner together on Dec. 30 and have been dating. The magazine attributed interims in the relationship to the stars' respective busy careers and their seeing each other only when schedules permit.

E! News said in August that the two had begun seeing each other in late June, following Lawrence's breakup with her "X-Men" movies co-star Nicholas Hoult. Martin and his wife, Oscar-winner Gwyneth Paltrow, 42, had jointly announced in March that they were separating after 10 years of marriage and two children, daughter Apple, 10, and son Moses, 8.

Relationship rumors began after Lawrence and the British-born Martin were seen together publicly on July 1, conversing at an after-party following Coldplay's concert that night at London's Royal Albert Hall. Lawrence attended Martin's performance at the iHeart Radio Music Festival in September, as well as his guest appearance with the band Kings of Leon at the Hollywood Bowl in early October.

Late that month, however, reports circulated that the two -- who had never publicly acknowledged they were dating, and were photographed together only once during that time -- had broken up.

The stars' respective representatives have not commented.

Lawrence announced in May that she will play Joy Mangano of Nissequogue, a divorced mom of three living in Smithtown in 1989 when she first began finding success with her invention the Miracle Mop. "Joy" is scheduled for a Christmas release.
