LATEST: An official wedding invitation to Britney Spears and Kevin Federline's 2004 wedding has been sold on auction website eBay for $2,150 (GBP1,190). The invitation, which also comes with a candle from the reception and is embossed with the couple's initials, was purchased by internet gaming company Goldenpalace. The latest purchase will be added to the site's growing collection of bizarre Britney Spears memorabilia, which includes the star's home pregnancy test, a pacifier used by Spears and her younger sister JAMIE LYNN, as well as a half-full bottle of water left in the hospital by the pop star after she gave birth to her son, Sean Preston. DARRICK GUY, who represents 24/7 Auctions, the seller of the invitation, told website TMZ.com they obtained the invite from a female guest at the nuptials. According to Guy, the guest has "relations to the groom's family".
