Jennifer Lawrence may be notoriously private, but that didn't stop her from supporting her supposed beau.

Lawrence was spotted backstage at the iHeartRadio Music Festival, where Chris Martin and his band Coldplay performed, notes Just Jared.

The actress was also dressed to impress. She wore a studded Emilio Pucci crop top, black pants and black heels. She is usually much more casually dressed, so Lawrence showed off a new side to her everyday style.

Lawrence traveled to Las Vegas to support Martin after being spotted at another Coldplay concert earlier in the week, but she wasn't the only one that made an impression.

Chris Martin also put on quite the show. He and the rest of Coldplay performed five songs: "Clocks," "Viva La Vida," Paradise, "Ink" and "Sky Full of Stars."

At the Sept. 17 Los Angeles concert, Martin looked around until he spotted Lawrence.

"Chris gave a good look around the room and then spotted someone up on the balcony," a source said. "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."

Lawrence, who was trying not to attract attention, arrived to the concert just before it started. She was accompanied by a group of friends.

As the show went on, it became clear that Lawrence was a big fan.

It was also recently reported that Martin and Lawrence have been keeping their relationship under wraps by spending time together at Martin's Malibu home.

"Chris seems very respectful of Gwyneth and feels more comfortable spending time with Jen away from his family," People said.

But they have also been spotted out in public having dinner. One of the times, she joined Martin and his friends at the Chateau Marmont.
