The KISS frontman and his actress wife got an assist from their kids, Nick and Sophie, who literally had a hand in helping to spread the word.

The beautifully written invite contains a hand-drawn family picture by Nick. Sophie, meanwhile, took charge of the writing duties, penning the quirky verbiage "Classy Cocktail Attire Requested, although we know some Rockstar attire will be worn."
