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.
