LOS ANGELES - The wedding itself will definitely be one of those "Charmed" affairs, meaning it's probably going to end in tears -- but Phoebe Halliwell's gown could make some size zero future bride, or any size fan, very happy.

The WB and Spelling Television are auctioning off the wedding dress Alyssa Milano's character will wear in the upcoming episode "Marry-Go-Round." Designed by St. Tropez, the full-length gown has an off-the-shoulder neckline, and also features beading and lace on the bodice and train.

The dress will be put up on online auction site eBay.com beginning Tuesday, March 12 and run until Thursday, March 21. Bidding will start at $10 and proceeds from the auction will benefit the Motion Picture and Television Fund.

On the March 14 episode, Phoebe and Cole's (Julian McMahon) nuptials will be disrupted when The Source takes over the groom for its own demonic purposes. Rap star Coolio guest stars as a very unwelcome guest.
