Gene Simmons & Shannon Tweed Are Married!

It’s official – Gene Simmons and Shannon Tweed finally tied the knot!

After nearly 30 years together, the 62-year-old KISS rocker married his long-time partner on Saturday in an outdoor celebration at the Beverly Hills Hotel, a rep confirmed to PEOPLE.

The couple exchanged vows in front of nearly 400 guests, including their two children – Nick, 22, and Sophie, 19. Sophie served as the maid of honor for her mother, and fellow KISS member Paul Stanley was also in the wedding party.

For their first dance: “At Last” by Etta James.

Congrats to the happy couple!
