Jennifer Lawrence and Chris Martin have reportedly stopped trying to hide their romantic relationship from the public!

The 24-year-old "The Hunger Games" star and the 37-year-old Coldplay frontman were reportedly spotted "making out" at the iHeartRadio Music Festival which took place over the weekend at the MGM Grand Garden Arena in Las Vegas, Nevada.

"At around 7:00 p.m. on Friday night, Jennifer and Chris were making out backstage in an area that only allows security and a select group of celebrities in," an eyewitness source close to the production of the event told Radar Online, as quoted by The Mirror. "She had her arms around his neck. They were kissing passionately before he took the stage!"

And when the hunky British musician hit the stage to perform, "Jennifer was watching from backstage and looked like the proudest girlfriend in the world!" added the tipster.

The source dished that the couple is already done hiding their romance from the public: "They spent the entire weekend together. They were not trying to hide it at all."

A tipster also told Us Weekly that Lawrence has had a crush on Martin since she was a teenager. In fact, she is a huge fan of the British rock band. "It's a fantasy come true [for her]," the insider said.

Another source told the entertainment and celebrity magazine that the singer-songwriter "has fallen in love" with the Oscar-winning actress. "It's the real deal."

The relationship between the Lawrence and Martin is reportedly becoming so much serious that the two are said to have started moving in together.

Last week, Lawrence was seen close to Martin's £10 million home in Malibu, and friends of the pair said the actress is there "all the time," The Mirror reported.

"This is it for Chris. He adores her and they've become inseparable. She has pretty much moved in," a pal of the pair told the British newspaper. "It would be fair to say Jennifer has more than a few belongings at his place."
