And by Westminster Abbey I mean a TV studio full of judgment."William & Kate's Wedding: Hollywood 411 Special Edition, which looks back at the couple's relationship, and 25 Favorite TV Weddings of All Time, a countdown of TV's most memorable "I Do's."William & Kate's Wedding airs Friday at 10/9c and 25 Favorite TV Weddings of All Time airs Saturday at 7/6c.
