Cheryl Cole's pet pooch's thong nicking antics revealed!

London, Nov 5 : Cheryl Cole's pet dog has developed a rather bizarre hobby-it picks up the singer's lacy underwear and buries them in her back garden!

The stunning X Factor judge recently caught her Chihuahua, Buster, digging a hole in her lawn with a thong hanging from his mouth.

"My dog digs holes and puts my knickers in the ground - but then I shouldn't be telling you that," The Sun quoted her as saying.

She added: "It's disgusting, I have no idea why he would do that." Cheryl uncovered Buster's knicker antics at the Music Industry Trust Awards at London's Grosvenor House Hotel on Nov 3.

It's not the first time that Buster has displayed her naughty ways- earlier this year it cocked its leg on a carpet at a venue for the The X Factor auditions.
