An invitation to Britney Spears' 2004 wedding to Kevin Federline and unseen photos form the "big day" are up for sale on e-bay. Yes, there is an on-line auction going on right now with memorabilia from Spears and Federline's wedding day. The items have reportedly been put up for sale by Federline's grandfather following the death of his wife, according to TMZ.com.Up for auction is a wedding invitation made from ivory lace and studded with Swarovski Crystals which was sent to Federline's grandparents Earl and Betty Story. The lot also includes a rose petal holder given to guests on the big day, a napkin ring which features a note from the former couple, and a number of previously unseen shots from the wedding.

While we have not yet heard from either Spears or Federline yet on this case, you can bet that neither would be really happy that someone is trying to profit off of their "big day" from back in 2004. The couple does have two kids together, Sean Preston and Jayden James, and divorced in 2007.
