McBusted have written a song about breasts.

The McFly and Busted supergroup - made up of Tom Fletcher, Danny Jones, Dougie Poynter, Harry Judd, James Bourne and Matt Willis - have revealed their latest track was inspired by boobs and hope it will be considered an ''appreciation'' of the female physique, reports The Daily Star.

Matt, 31, said: ''We have been writing a lot recently. I was writing with Dougie Poynter last night. We were writing a song about boobs.

''We couldn't write an album just about boobs - well, we could, me and Dougie would buy it.''

Dougie, 26, explained: ''It's an appreciation.

''Matt and James Bourne have been writing too, or we might write some more stuff about boobs.''

Meanwhile, the boys - who are about to bring their sold-out UK tour to a close with a British Summer Time gig in London's Hyde Park on Sunday (06.07.14) - said they are ''pumped'' about the performance, although Matt admitted it has been an emotional time for the group.

James, 30, said: ''We are super pumped.''

Matt added: ''This gig marks the end of the honeymoon period. I don't want to sound all lame but it's been everything I wanted it to be.''
