Robbie Williams has announced that he's auctioning off some of his ''prized possessions'' for The Donna Louis Children's Hospice.

The 41-year-old singer - who is a patron of the children's charity - revealed in a video on his Facebook page that he is putting 150 personal items up for auction, including hand-written lyrics for 'Let Me Entertain You' - estimated to raise £6000 -, a cream two-piece suit he wore in the video for 'Radio' and some of the many awards he's won over the years.

Robbie said: ''It's a privilege for me to be a patron of The Donna Louise Children's Hospice. It makes a real difference to these children whose lives have been tragically limited.''

''The sale gives a great opportunity for bidders to know their money will go to such a fantastic charity, whilst also taking home some of my most prized possessions that have been personal markers of my career and life so far.''

The auction, named 'Doing It For The Kids' in reference to his 2000 duet with Kylie Minogue, will be taking place in Bonhams in Knightsbridge, London, at 3pm on 15 July, and a live stream of the auction will also be available on the former Take That star's Facebook page.
