Rocker Jon Bon Jovi credits fear with keeping his marriage alive 20 years after he wed high school sweetheart Dorothea Hurley because he's terrified of her.

While other showbiz unions have fallen by the wayside, the Bon Jovis are stronger than ever, and celebrate their platinum wedding anniversary in 2009.

The hitmaker explains the secret to their happiness, "Let's get that right here, right now. I'm afraid of my wife." He adds, "Trust me, she is the best. I am very happy."
