Jennifer Lawrence and Bradley Cooper are definitely good friends, but a new report suggests they are more than that.

They are apparently spending a lot of time together off screen and are ready to take their relationship to the next level.

"Everyone knows they have great chemistry... and their passion, which they've tried to hide, is undeniable," the source told OK Magazine.

"But they also have a lot in common, and they really make each other laugh."

The 40-year-old, who recently split from girlfriend Suki Waterhouse, reportedly left his younger girlfriend for his co-star. And though he broke it off before making things official with Jennifer, the pair had been secretly texting for some time now.

"He wanted to end things properly with Suki," the source said, adding that Bradley was texting Jen while out with Suki at the Vanity Fair Oscars afterparty. "He sent her a message saying that he wished she was there with him," the source said.

As Lawrence is spending time with her Serena co-star, her boyfriend Chris Martin is on a vacation with his ex-wife Gwyneth Paltrow and their children Apple and Moses.

According to a report in OK Magazine, the ex-couple looked happy as "Chris took their children on a boat to do some tubing and then watched them snorkel near the shore."

A source also revealed they rented a villa together for the five-day trip.

Martin and Paltrow announced their split on Paltrow's website, Goop. She wrote that they "decided to separate" and would "consciously uncouple and coparent."
