Actress Jennifer Lawrence and rocker Chris Martin have reportedly split after four months of dating.

The 24-year-old Oscar winner was first linked to the 37-year-old Coldplay frontman in June not long after they both came out of long-term relationships.

The pair, who have never commented publicly about their relationship, were first photographed together in September when Lawrence showed up to support Martin at the 2014 iHeartRadio Music Festival.

Most recently The Hunger Games star attended on of the musician's performance with Kings of Leon at the Hollywood Bowl earlier this month.

But the whirlwind romance is already over, according to E! Online.

Lawrence previously dated her X-Men: First Class co-star Nicholas Hoult on and off until their split earlier this year, while Martin famously "consciously uncoupled" from his wife of 10 years, actress Gwyneth Paltrow, in March.

Late last year Lawrence described her dream man as "somebody to watch TV with me" and who "isn't afraid to fart in front of me."

"I'd rather have just a peaceful time. (Those) are deeper because you can be your true self with somebody, and somebody can be their true self with you," she told the November issue of Vanity Fair.
