The Coldplay concert was quite the star-studded event last night.

Chris Martin and the boys rocked out at the Ace Hotel Theatre in L.A. Wednesday to a crowd full of adoring—and famous—fans. Along with Martin's girlfriend Jennifer Lawrence, E! News learns that One Direction cutie Harry Styles attended the show with a mystery girl.

Wearing a white T-shirt, skinny jeans and his signature wide brim hat, Styles was seen "singing along" to the tracks and "at one point he whistled using both hands like a referee whistle. He's also dancing and singing," a source tells us, adding that the singer was "in his own world completely enjoying the music."

There's no word who his gal-pal companion was, but the eyewitness states they seemed to have more of a flirty friendship than anything romantic.

Also in the audience was former flames Zoë Kravitz and Chris Pine, however, it doesn't look like this was a couple's outing, either. "Zoë and Chris have known each other for a few years. They get a long great and are good friends," a different source tells E! News.

"Zoë has always been friends with her exes. She's one of those girls that has a lot of guy friends and even if there's been a past romance…she'd go back to being just friends. But knowing Zoë, and Chris being as hot as he is, anything is bound to happen."

While Martin sang to a ~~sky~~ room full of stars, there was one celeb in particular that was captivated by the musician—J.Law (duh).

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

And even though Styles was in the row directly behind her, Lawrence remained fixated on Martin. "Jennifer stared adoringly at Chris, both hands in the hair, dancing and singing along to 'Magic,'" the source added of the Beat Music-sponsored event. After the show ended, the actress and her friends were ushered out via a private exit.
