Planning a wedding? You could walk down the aisle in a celebrity dress. Blake Shelton's ex-wife Kaynette is selling her wedding gown on eBay.

The strapless designer Demetrios wedding gown is a size 6, with a starting bid of $700. It was the dress Kaynette wore when she said 'I do' to Shelton in 2003. The couple called it quits 3 years later. I wonder why she kept it so long.

If this is the new trend, I want Shania Twain's dress she wore when she married Mutt Lange.  She doesn't need it now that she's happily remarried; to the husband of the woman Mutt was caught cheating with.
