The Clintons' Over-the-Top Wedding Details

The father of the bride, Bill Clinton, seems to be losing weight almost as fast as he's spending money on Chelsea's lavish wedding.  INSIDE EDITION reports on the latest expenses of the big day.

Chelsea Clinton's wedding could be more expensive that we thought. Experts now say her big day could cost anywhere from 3 to a mind-blowing $5 million.

Robin Roberts on Good Morning America called it, "the biggest wedding of the summer."

The Clintons are reportedly springing for the best of everything when it comes to planning their only daughter's wedding. And that includes $15,000 for port-o-potties, of all things.

The site of the wedding, Astor Courts in Rhinebeck, New York, is a 50-acre estate that requires extra toilets for the 500 expected guests.

INSIDE EDITION's Megan Alexander checked it out:

"I'm inside this luxurious 28-foot restroom trailer. From the marble sink to the mahogany paneling at the privacy of your own stall to the high-end artwork on your walls, this is the perfect fit for the A-list guests coming to see Chelsea say 'I Do.' "

And has the father of the bride lost too much weight in anticipation of giving Chelsea away? Last spring President Clinton revealed that Chelsea was encouraging him to slim down.

Clinton joked, "She told me the other night, she said, 'Dad the only thing you gotta do is walk me down the aisle and you gotta look good.'  So I said, 'Well, what's your definition?' and she said, 'Oh about 15 pounds.' "

But when he appeared at a charity event in Minnesota on Sunday he looked almost gaunt, with his neck not even filling out his shirt collar. The whole family has clearly gone into overdrive to prepare for Chelsea's walk down the aisle.
