Didn't get an invite to the rock 'n' roll wedding of the century? Neither did we. Lucky for us both, Entertainment Tonight's Mark Steines did score an exclusive invitation to take us inside Saturday's wedding of Kiss legend Gene Simmons to his longtime girlfriend, Shannon Tweed, and ET cameras went along for the ride. Monday's edition of the program featured footage from the nuptials, and also revealed more details about the big day.

The groom walked the aisle alone in a classic black tuxedo with a silver tie, fist bumping guests from an audience of 400 that included 'Survivor' creator Mark Burnett and Duane "Dog the Bounty Hunter" Chapman. The bride wore a Priscilla of Boston gown and was accompanied by her mom, Louise, for her stroll down the aisle. Shannon carried a bouquet of ivory roses and had a surprise in store for Simmons when it was time for her to say, "I do." Watch the segment below to see what she did to make the audience laugh.

After 28 years of dating, Simmons and Tweed finally tied the knot Saturday at the Beverly Hills Hotel and about 4oo guests were on hand to witness the ceremony. The pending nuptials -- and the legendary lothario's fear of commitment -- have been a major plot point on 'Gene Simmons Family Jewels,' and the ceremony is sure to be featured prominently on the upcoming season of the reality program.

The new season of 'Family Jewels' premieres tomorrow (Tuesday, Oct. 4) on A&E and the big wedding episode airs Oct. 18. In the meantime, tune in to Entertainment Tonight tomorrow for exclusive footage from the couple's reception, which included a three-song set from Kiss -- in traditional wedding attire, not their own traditional stage make-up and outfits.
