Move over Coldplay fans, Chris Martin has a new very dedicated fan in Jennifer Lawrence.

The singer’s rumoured love turned up to his second concert in three days, travelling all the way to Las Vegas, Nevada, on Friday to watch him perform at the iHeartRadio Music Festival.

And the 24-year-old made sure that her new boyfriend could spot her from stage in a sexy midriff bearing ensemble.

Supportive girlfriend: Actress Jennifer Lawrence was spotted backstage at the iHeartRadio Music Festival in Las Vegas, Nevada, on Friday where rumoured boyfriend Chris Martin was performing

While normally a bit eclectic when it comes to her off the red carpet style, there was no baggy tops or comfy pants for the Hunger Games star on Friday night.

Instead, the Academy Award winner ensured she stood out from the crowd in a cropped embellished short sleeved top with a pair of ultra-tight high waisted black jeans.

The star – who is known for her down-to-earth style sensibilities – glammed up the look further with a pair of strappy stilettos, studded belt and an unmissable gold panelled designer bag that seemed to take inspiration from a fortune cookie.

The star, who wore her blonde locks with one side behind her ear and the other side curled – seemed determined as she walked backstage, no doubt wanting to be there to see Coldplay’s first song.

But Jennifer was not the only one trying to be impressive on Friday night.

While Coldplay’s songs may largely be ballads, the 37-year-old front man danced around stage like he was a female pop star.

At one stage, the former husband of Gwyneth Paltrow, sat at the piano but threw himself backwards so that he looked like a ballerina.

An insider told E! News that the 24-year-old was singing along: ‘She knew every word to every song and there was a glisten in her eye as she watched Chris perform.
