Coldplay frontman Chris Martin wrote a song from the band's forthcoming album Mylo Xyloto in his daughter's doll's house, according to The Sun newspaper.
In an interview with the tabloid, Martin said that 'Charlie Brown' was "the only song we ever wrote in a doll's house. I turned it into a studio because my daughter didn't like it."
Martin and his wife Gwyneth Paltrow have a daughter, Apple, and a son, Moses.

The frontman also said that the new album – released on October 24 in the UK and October 25 in the US – is a concept album and is "dangerously close" to sounding like a musical.
He said of the band's fifth studio album: "Our new record is sort of a story – it's not quite a musical, but it's dangerously close."
Anyone trying to unlock the riddle of the tongue-twisting title Mylo Xyloto will likely be disappointed, as Martin recently confessed the words are meaningless.
He told MTV: 'It doesn't mean anything… It sort of has a nice appearance to it, with all those o's."
Meanwhile, fans have been warned to beware of scams as tickets for Coldplay's arena tour go on sale tomorrow.
Would-be gig-goers are advised to beware suspicious websites that offer tickets to sold out events. Industry insiders say consumers should check whether websites are endorsed by recognised brands.
