Singer Annie Lennox is helping the homeless in her native U.K. by donating a treasured hat to a charity auction.

The former Eurythmics star has handed her stylish, leopard-print fedora to bosses at St Mungo's Community Housing Association for inclusion in an online sale.

The headwear is listed on auction website, and bidding on the item ends on Sunday (28Oct12).

All proceeds will go towards the St Mungo's charity, which provides support and housing for the homeless.
