Coldplay performed at the Ace hotel in downtown Los Angeles on Wendesday night, and while Chris Martin's girlfriend Jennifer Lawrence was at the show, the British singer and his much younger lady love left separately. Martin Lawrence are proving to be far sneakier than we thought!

As you know, J. Law went to Coldplay's concert in New York in August, and she's long been a fan of the British band -- and Chris, obviously! Last week the two went out to dinner in Beverly Hills, and after that they were holed up at Chris' $14 million Malibu mansion.

J. Law arrived fashionably late, and a source tells Us Weekly:
    "Just before the show was supposed to start, [Jen] walked toward the stage, surrounded by a couple [of] girlfriends, trying to find their seat. 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."

Lawrence wore a "slinky, dark blue dress," and sat on the balcony, and a source at the show tells the mag, "Chris gave a good look around the room and then spotted someone up on the balcony. 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."

OMG!

Other celebs at the show included Chris Pine, Zoe Kravitz, Harry Styles and Matt Damon. Funny, because Matt is Ben Affleck's BFF, and Ben famously dated Chris' estranged wife Gwyneth Paltrow, so we wonder if the boys ever hang out and ernd up chatting about Mrs. Goop?
