Chris Martin will go on tour with his Coldplay bandmates this fall and his rumoured girlfriend Jennifer Lawrence will reportedly join him on the road.

According to a source, Coldplay will be announcing in the next several weeks that they are embarking on a tour across the US to promote their new album "Ghost Stories", reports radaronline.com.

"This won't be a huge tour as the band has done in the past, and will only be stopping in the major markets such as Los Angeles, Chicago and New York,` added the source.

Martin, who split from actress Gwyneth Paltrow in March after 10 years of marriage, and Lawrence, first sparked dating rumours in July. And now, it is said that she will accompany him to his tour.

`Chris doesn't want to be away from his kids, Apple and Moses. Girlfriend 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 bandmates really like Jennifer," said the source.
