Jennifer Lawrence and on-and-off boyfriend Chris Martin are rumored to be back together but the couple seemed to have confirmed the news when they partied together for the birthday of One Direction's Harry Styles.

A report from Just Jared claimed that Jennifer Lawrence and Chris Martin attended the party in Isabel in Los Angeles.

The other celebrities who attended Harry Styles' birthday were David Beckham, Adele, Zach Braff, Adam Levine, Courtney Cox, Kendall Jenner and Cara Delevingne.

Jennifer Lawrence has been rumored to be getting back with on-and-off boyfriend Chris Martin after they split late last year following a two-month relationship. However, during the New Year holiday, the Coldplay frontman and the "Hunger Games" actress were snapped trying to be incognito when they had lunch at a restaurant.

Previous rumors pointed to Gwyneth Paltrow as the reason for Jennifer Lawrence and Chris Martin breaking up because she was always intervening into the relationship.

But the Goop founder denied those rumors as she said that she's has no quarrel with her ex-husband's choice in women.

In an interview with Howard Stern, Gwyneth Paltrow said that she like Jennifer Lawrence for Chris Martin.

"Who says I don't approve? Why not? Why is it going to be an issue? I respect him as the father of my children. It's his life and it's his decision and I do think that he loves the kids so much, and I don't think that he would be with someone that wasn't great. And if I'm wrong, I'll come back here and I'll tell you," she said.

Gwyneth Paltrow said that she's friends with her ex-husband for the sake of their children, who will spot if they ever fake their feelings toward each other.

During the Christmas holidays, Chris Martin and Gwyneth Paltrow were spending so much time together which, coupled with Coldplay frontman's split from girlfriend Jennifer Lawrence, sparked reunion reports.
