Lily Allen is giving fans the chance to have a "boozy evening" at her fashion boutique and take home a free handbag.

The pop star has decided to offer the great prize to her followers on twitter for Twit Relief, an online auction set up by the micro-blogging site to raise money for British charity and annual TV telethon 'Comic Relief', which aims to raise money to help people living in poverty in Africa and a host of other good causes.

After pondering on what she could do to assist, Lily came up with the idea to let one of her follower's have a night at her London fashion boutique - which she runs with her sister Sarah Owen - and maybe even dinner with the singer.

In a series of posts on her twitter page, she wrote: "What shall I offer up for Twitrelief? Am struggling to come up with something interesting . Ok how about, a follow, a handbag of your choice from my personal collection and a boozy evening at Lucy in Disguise for you and 4 friends . You'd all get free hire of an amazog dress. Each and I might throw in dinner too. Whadya say? (sic)"

Anyone interested in the prize needs to log on to a special eBay page ( which has been set-up to receive bids on the celebrity auctions

However, Lily's prize is not yet listed on the website.

As well as the celebrity donated prizes on offer - which include a Mulberry handbag from Alexa Chung and a walk-on part in the next film by 'Notting Hill' writer Richard Curtis - Twit Relief winning bidders will also be followed by their chosen celebrity on twitter for 90 days and have their tweets re-tweeted.
