An official invitation to BRITNEY SPEARS' second 2004 wedding ceremony is being offered for sale on internet auction site eBay. Fans keen to snap up the unique memorabilia will have to pay upwards of $1,000 (GBP555) - the starting price. Sellers, 24/7 Auctions, will also send the top bidder a candle from the nuptials, which features the initials of Spears and her husband Kevin Federline. The invitation and candle were given to an unnamed guest at the ceremony, who has decided to cash in the memorabilia. The September marriage to Federline was the second wedding for Spears in 2004 - in January she spent 55 hours as the wife of childhood pal Jason Alexander before it was annulled.
