Chris's bizarre baby video

Coldplay singer Chris Martin has celebrated the birth of his daughter Apple in an unusual way - by recording a spoof glam rock video.

Visitors to the website Coldplay.com are able to click on a link that takes them to a video by band 'The Nappies' - which are the members of Coldplay dressed in hair-metal wigs.

The message on the website says: "In celebration of the birth of Apple Blythe Alison Martin, we are pleased to introduce you to another new arrival. Please click on of the links below to see the latest addition to the Coldplay camp"

Stripped to the waist and wearing a spiky blond mullet wig, Martin sings about Gwyneth Paltrow's changing hormones, nappies, poo and even his wife’s breasts.

He raps, "I'll be there through the thin and the thick / I'm gonna clean up all the poo and the sick."

"Your boobs gone up 10 times their size, cups gone up from A to D, that's bad for you, it's fun for me."

The video is available to watch for one week only.
