Gene Simmons and Shannon Tweed's Rockin' Reception

By
KISS rocker Gene Simmons finally decided to settle down and marry his long time girlfriend Shannon Tweed this weekend, and ET's Mark Steines was at the couple's rockin' reception to check out the celebration.
Gene and Shannon's daughter Sophie took the stage first and serenaded her parents with the Etta James's classic song At Last. Son, Nick followed his sister's performance with a rendition of The Doors' hit song Roadhouse Blues. Not to be outdone by his children though, Gene took the stage and sang his classic song Shout It Out Loud.
Besides their families at the reception, Gene and Shannon were joined with friends Bill Maher, Hugh Hefner, Dog The Bounty Hunter and Rob Zombie.
