Heidi Montag & Spencer Pratt’s Upcoming Wedding Details

Yeah, it’s gross, but like a gory car accident on the freeway, we can’t help but look. Heidi Montag and Spencer Pratt are set to have their televised wedding on Saturday and here are some more of the dirty deets.

Heidi’s dress (I hope she has the unabashed gall to wear white) was designed by Monique Lhuillier and costs $19,000. Maid of honor will be Heidi’s sister Holly Montag and Spencer’s sister Stephanie Pratt will take on the role of bridesmaid.

With slightly more than 200 people on the guest list, celebrities confirmed to attend are Michael Bublé, Pete Wentz, Ashlee Simpson, Khloe Kardashian and Perez Hilton. Even though she’s made no secret of her aversion to the relationship, Heidi’s mother Darlene Egelhoff will be in attendance along with Montag’s entire family.
