Ageing rocker Gene Simmons proposed to his longterm partner Shannon Tweed over the summer (11) after deciding it was time for him to "grow up".
The 62-year-old Kiss star has lived with the model since 1985, and after 26 years of dating they will exchange vows in Los Angeles on Saturday (01Oct11).
Simmons has opened up about his relationship with Tweed in a new interview with ET Online and the singer admits she is the only woman he has ever declared his love for.
He says, "It is time for me to grow up. I'm 62. I've been doing a lot of wacky stuff for an awfully long time... and there's nobody I've ever said I love you to.
"I even find it difficult to say 'I love you' to my mother. But I love Shannon with all my heart and all my soul, and always will."
The couple is parents to 22-year-old son Nicholas and daughter Sophie, 19.
