The 'Coldplay' frontman, who casually dated Jennifer Lawrence for a year following his split from ex-wife Gwyneth Paltrow in March 2014, is reportedly smitten with the British actress, 31.

A source close to the 38-year-old rocker said: "She puts a huge smile on Chris' face. He's happier than he's been in a long time."

The couple haven't been dating for very long, but the 'Magic' hitmaker "isn't seeing anyone else."

The insider told Us Weekly magazine: "He just wants to settle down again."

The pair made no attempt to hide their romance as they kissed and danced along the streets in Paris recently.

The source said: "They were with friends in Paris but spent as much time alone as they could."

Rumours about the pair first surfaced when they were seen enjoying at intimate dinner date at Lucali in Brooklyn, New York in August shortly after his split from 'Hunger Games' star Jennifer, 25.

A source said at the time: "He has moved on quickly and has been seeing Annabelle Wallis for about a month.

"He visited her while she was filming in Vancouver and really likes her."
