Items from Nicole Kidman's wedding to country singer Keith Urban are being auctioned off on website eBay. One guest at the Australian ceremony has decided to sell mementoes from last month's (JUN06) highly-publicised event - up for sale are a menu from the reception, a Tiffany desk clock with the inscription 'A Moment In Time, June 25 2006, Nicole and Keith', and a piece of the wedding cake. According to PageSix.com, each item will go on sale with a starting bid of $5,000 (GBP2,800).
