The Chris Martin-Jennifer Lawrence romance speculations have got a new reason to spread. The 24-year-old "Hunger Games" actress was spotted at the concert of "Coldplay" singer at Los Angeles' Ace Hotel on Wednesday night. The actress tried her best to cover her face from paparazzi and did not answer any questions, but many eyewitnesses revealed to media that Chris "serenaded" his lady love with his voice.

Lawrence reportedly arrived at the concert with his girlfriends much before the show started and took her seat in the balcony just in front of singer Harry Styles, reveals E! News. The actress' presence was acknowledged by Martin when he entered on stage to kick off his performance. He reportedly "kept looking at her" during the show "smiling, pointing and singing to her," revealed a source to the website.

"Jennifer was like the center of Chris Martin's attention last night. He was like singing to her the whole performance. Smiling, winking. It was like a personal serenade. She wasn't shy at all," tells an eyewitness tells HollywoodLife.com exclusively.

The gorgeous actress reciprocated by singing along the lyrics to his song "Magic" and dancing all the time with her hands up in the air.

For the concert, Jennifer wore an all-blackish blue attire that consisted of a semi-sheer skirt with a thigh-high split on one side. The blonde haired actress teamed up her sexy skirt with a front buttoned black blouse. She wore minimal makeup and let her cropped wavy tresses fall loosely over her face. The "American Hustle" actress looked casual yet stylish by wearing a long silver chain around her neck.

It was the first time that J Law was spotted publicly after her nude photo hacking scandal. The actress acted normal during the concert, but tried her best to hide her face from the photographers when she exited from the back door. The actress even went to great lengths to put all her hair over her face and bend her face down to her knees when she climbed into her car. Check out her pictures here.

Jennifer acted like the "biggest fan" of Chris Martin during the show and had a huge smile on her face all the time, an eyewitness told HollywoodLife.com.

"She had a huge smile on her face and was friendly, not stuck up at all. She just acted like a normal person. After the show, she went backstage with her friends. It was a very intimate gig, a historic theater. Just very chill and cool. And it obvious to everyone that they are an item," added the source, according to website.
