Jennifer Lawrence will reportedly join Chris Martin on his Coldplay tour later this year.

The couple only started dating in June, but it appears their new romance is getting fairly serious as the 24-year-old actress is set to accompany the frontman, 37, when his band hit the road in the autumn.

A source told RadarOnline.com: ''Jennifer Lawrence will be part of the entourage. She has some down time in her schedule at the moment, and is having so much fun with Chris. Chris' sense of humour has genuinely surprised her, and his band mates really like Jennifer.''

Meanwhile, the hunky singer, who split from Gwyneth Paltrow in March after 10 years of marriage, has reportedly been pulling out all the stops to woo the blonde beauty, including writing love songs about her.

A source said previously: ''He writes her songs and loves taking her to private romantic spots. Chris is sweeping Jen off her feet. That's his thing.''

Jennifer initially told her friends that her relationship with Chris, who has daughter Apple, 10, and son Moses, eight, with Gwyneth, wasn't serious, but she has become increasingly attracted to him since watching him perform in the UK earlier this summer.

The insider explained: ''Jen was blown away at his London show.

''His music is absolutely part of the attraction. The better she gets to know him, the more she likes him.''
