Chris Martin reportedly serenaded Jennifer Lawrence at his gig last night.

The musician performed with his band Coldplay at the Ace Hotel Theatre in Downtown Los Angeles on Wednesday evening, to a packed out crowd.

It is rumoured Chris and Jennifer are currently dating, following his split from wife Gwyneth Paltrow earlier this year. The American Hustle star also recently broke up with her boyfriend Nicholas Hoult, but neither she nor Chris has confirmed the supposed romance.

The 24-year-old beauty is believed to have been in attendance at the concert yesterday, arriving just minutes before it began.

"Just before the show was supposed to start, Jennifer Lawrence walked toward the stage, surrounded by a couple girlfriends, trying to find their seat," a source told Us Weekly.

"They looked a little rushed, like they wanted to get to their seat before the show started so someone on the theatre staff helped them out."

Jennifer is said to have looked "pretty" in a casual dark blue dress, and apparently took a seat on the balcony of the venue. As Chris stepped out onto the stage, the publication claims he scanned the audience for his rumoured girlfriend, eventually spotting a person who is thought to have been her in the crowd.

"Chris gave a good look around the room and then spotted someone up on the balcony," the insider continued. "He pointed and said, 'Aha! I see you!' and then smiled and waved. He kept looking up in the direction during the show and smiling, pointing, singing to her."

Jennifer wouldn't have been the only A-lister in the audience, as Matt Damon and Harry Styles also attended.

This supposed serenading comes after Jennifer was spotted taking a stroll near Chris' Malibu beach house last week.

British singer Chris was with his estranged wife Gwyneth for ten years, and the pair have kids Apple and Moses together. His ex is said to be comfortable with the new relationship

“Her take is, 'Hey, he could do worse," a source added. "She just wants him to be happy."
