Kevin Federline's grandfather, Earl Story, has put up several personal items on eBay -- items from his grandson's relationship with ex wife Britney Spears.

Among the bounty is the invitation to the couple's wedding, with bids for it starting at $1,000. Others include a hat Kevin wore to an awards show with Spears, an invitation to one of Brit's baby showers and 14 wedding photos, some of which might never have been seen before in the press.

Spears and Federline married in 2004 after just three months of dating. They had two sons, Sean Preston and Jayden James, then divorced after two years of marriage.

Story reportedly has Federline's approval for selling the items.
