Jennifer Lawrence dating Chris Martin reports have heat up as the new couple were spotted "kissing passionately" during his performance in Vegas. Meanwhile, his ex-wife Gwyneth Paltrow has drawn up a schedule to make sure the Coldplay frontman doesn't miss out on their kids.

According to the Radar Online report, Jennifer Lawrence is dating Chris Martin and that two are not hiding it anymore.

"At around 7pm on Friday night, Jennifer and Chris were making out backstage in an area that only allows security and a select group of celebrities in," a source told the tabloid. "She had her arms around his neck. They were kissing passionately before he took the stage!"

When the Coldplay singer was performing on stage at the MGM Grand Arena, Jennifer Lawrence was backstage and "looked like the proudest girlfriend in the world!"

Two weeks ago, the "Hunger Games" star appeared to be unaffected by the tabloids reports about Jennifer Lawrence dating Chris Martin, as well as the nude photo leak, as they spent a night together at Chateau Marmont in West Hollywood.

"They seem very comfortable in each other's company-and happy," a source dished out to E! News. "It doesn't seem like it's a new relationship. They seem super affectionate and at ease with each other."

Meanwhile, MailOnline talked to a source who claimed that Gwyneth Paltrow is happy that Jennifer Lawrence is dating Chris Martin.

But she makes sure that her former husband wouldn't miss out on the kids' life as she has drawn up a schedule that is favorable for everybody, according to Grazia magazine.

"She's drawn up a rota to balance his time living life as a bachelor and seeing Jennifer with honouring their many family commitments," an insider told the British magazine. "Gwyneth still has a lot of control over him, which isn't exactly desirable to prospective girlfriends."
