Gene Simmons and his girlfriend of 28 years, Shannon Tweed, were married this weekend before 400 guests.

The outdoor evening ceremony on Saturday at the Beverly Hills Hotel is the latest celebrity nuptials to have a second life as a television event. It is scheduled for an October 18th episode as part of the new season of A&E’s “Gene Simmons Family Jewels.”

The couple exchanged vows they wrote themselves, People magazine reported.

Guests included Hugh Hefner, Bill Maher and Simmons’ fellow Kiss members, with band guitarist Paul Stanley a member of the wedding party.

Tweed, 54, walked down the aisle in an ivory Priscilla of Boston gown and, according to TMZ, wore $2.5 million of diamonds — in addition to her engagement ring — for the first dance of the evening.

The couple’s daughter, Sophie, 19, served as maid of honor and son Nick, 22, created the illustration for the wedding invitation.

Simmons proposed to Tweed in Belize, in a moment that was captured by cameras for their A&E reality show
