Nick Lachey is reportedly selling off mementos from his three-year marriage to Jessica Simpson on eBay. The reality TV star has been busy putting together the auction of pictures and keepsakes from the TV shows and specials the couple recorded together, and will donate all profits from the sale to an educational charity. "Nick is going to hold on to the really sentimental stuff. There are a few things he can't bare to part with," a source said.
