Sophie Ellis-Bextor's charity T-shirt

Sophie Ellis-Bextor has created a bespoke T-shirt encrusted with Swarovski crystals for charity.

The 'Murder on the Dancefloor' singer has teamed up with UK fundraising charity Sport Relief - which aims to help underprivileged children in both Britain and third world countries - to design a one-off top, which is being auctioned off on eBay today (19.03.10).

Sophie has taken an official Sport Relief T-shirt - which was designed by David and Victoria Beckham and their three sons - and customised it in her own unique way as well as autographing it.

The Beckham family created a series of one-off designs and each T-shirt features 'The Beckhams for Sport Relief' logo, a combination of the footprints of each family member.

As part of the series of T-shirts, David took a distinctive self portrait showcasing his renowned soccer skills.

The official T-shirts are available at www.sportrelief.com and in UK stores Sainsbury's and TXMaxx, with at least ￡5 going to charity.

Sport Relief is one of the UK's biggest fundraising events and brings the entire nation together to get active, raise cash and change lives.
