Jennifer Lawrence and Chris Martin's blossoming romance has been the talk of the town these past few days. Recently, Daily Mail reported that the "Hunger Games" actress was spotted at the iHeartRadio Music Festival in Las Vegas where Coldplay frontman Chris Martin pulls "some serious acrobatics" while Lawrence watches.

"She was off to the side of the stage when he performed," a source tells PEOPLE. "After his set, she snuck back into his dressing room," the source adds.

According to People, Lawrence was seen backstage in a studded black crop top, matching denim bottoms and stilettos.

Furthermore, Daily Mail described her glammed up style. Reportedly, "the Academy Award winner ensured she stood out from the crowd" adding allure to her look with a "pair of strappy stilettos, studded belt and an unmissable gold panelled designer bag that seemed to take inspiration from a fortune cookie."

"She was watching him during his closed rehearsal and was singing along," says the source.

Reportedly, an insider told E! News that the 24-year-old was singing along.

"She knew every word to every song and there was a glisten in her eye as she watched Chris perform. She couldn't take her eyes off him," E! News' source said.

According to E! News, JLaw and Martin have been spending time together since late June. The couple's blossoming romance began circulating in August shortly after the actress had split from her boyfriend, Nicholas Hoult. Reportedly, Jennifer and Nicholas, 24, called it quits this summer but allegedly had a "very amicable" split after their careers made it difficult to sustain a relationship.

While the couple is said to begin dating just this summer, report says that the Coldplay frontman and the Academy Award winner do not seem to be new in the relationship. The onlooker said that the two are very much happy with each other's company.
