Lawrence, 24, and Martin, 13 years her senior at 37, were first linked in tabloids in August and some claim he is head over heels for the actress.
There may be some truth to that, given the way he performed at the festival. Witnesses said he played with more abandon than he has in years.
The aging frontman danced around stage like he was a female pop star, according to London’s Daily Mail, suggesting she is more than just a fan.
Lawrence was spotted in easy view of the stage. It was the second time second time she showed up at his conference in three days, the tabloid reported.
Lawrence wore a midriff bearing crop top and tight black jeans. It was one of her first appearances in public since nude photos lifted from her iPhone by hackers surfaced on the Internet.
The actress threatened to sue anyone who published the photos.
Earlier in the week, Jennifer also showed up at Coldplay show at the Ace Hotel in Los Angeles.
“She knew every word to every song and there was a glisten in her eye as she watched Chris perform,” a source told E! News.
