JLaw on Coldplay tour

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

The couple started dating only 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 hits the road in the autumn.

"Jennifer Lawrence will be part of the entourage," a source told RadarOnline.com.

"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 bandmates really like Jennifer."

The 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.

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

"Jen was blown away at his London show," the insider said.

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