"Monogamy is a very tough order. You’re in the prime of your life, you are attracted to other people, potentially, you have fantasies about that. It really runs the risk, if you will, if you’re not aware that you could maybe screw up a really good thing by doing that," Goldie recently told People.

"I’m sure I’ve been party to it, and Kurt’s been — we’re all normal this way. It’s like, 'You really liked that guy, didn’t you?' Or the woman says, 'You were looking at her.' My answer would be, 'Of course. Why not? She’s beautiful,'" she continued.

"Would you want a man who doesn’t look? Who doesn’t feel inspired by the beauty or the curves of a woman’s body? Or the way she is? I mean, come on," Goldie added. "We’re human beings. There is, I guess, an elasticity to the relationship. Otherwise it’s going to break, just like a rubber band."

Earlier this month, the longtime couple received matching stars on the Hollywood Walk of Fame. "Goldie to you, I owe my wonderful life. Simply put Goldie, I cherish you.
