Ashleigh Butler, the owner of Pudsey, who won Britain's Got Talent in 2012 announced yesterday that he had died.

On Instagram she posted: "I can't honestly believe I am writing these words. My handsome man is gone and I don't know what to do without him."

"My heart is broken and I don't know how I'm going to get through this. It hurts so much that my handsome man has gone and I don't know how I'm going to get through this. It hurts so much that my handsome incredible Pudsey Bear will never be by my side, where he belongs again."

"We only had 11 years together, but they were the best years ever. He was my one in a billion dog that will never be replaced," she said.

Pudsey is thought to have died after having acute leaukaemia. It's reported he was put to sleep.

Ashleigh and Pudsey rose to fame in 2012 winning the public vote of Britains Got Talent.  They went on to perform for The Queen at the Royal Variety Performance.  Then came Pudsey the Dog: The Movie - which featured the voice of David Walliams.

The last time Pudsey competed was at Crufts earlier this year.
