Gene Simmons & Shannon Tweed Wedding Announcement

Gene Simmons is finally revealing what Shannon Tweed said when he asked for her hand in marriage ... and she didn't say no.

Now, the couple is planning the wedding -- with invitations already sent -- complete with a sarcastic wedding announcement from their kids.

"After 28 years of loose strings, our parents have finally decided to tie the knot. Our mother will share our horrendous hyphenate of a last name and our father's life ... well, it doesn't change that much."

It continues on a heartfelt note -- saying, "But we will be united as a family in spirit and in title forever."

The wedding is set for October 1 at the Beverly Hills Hotel.
