An invitation to Britney Spears
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.
Also for sale is an invitation to Spears' baby shower and a photograph of her when she was pregnant with her son Sean Preston.
The items have reportedly been put up for sale by Federline's grandfather following the death of his wife, according to TMZ.com.
Spears and Federline divorced in 2007 after becoming parents to two sons, Sean Preston and Jayden James.
