Harry HamlinandLisa Rinnaknow a little something when it comes to love.

In this week’s issue of PEOPLE, the couple opens up about their nearly 25-year-old love story — and the secret to a successful, happy marriage.

“[The secret is] being diametrically opposite,” says Hamlin, 70. “I like going up to the mountains, and her idea of camping is anything below the 10th floor of the Four Seasons.”

The actor adds, “So I called her up and I said, ‘Do you want to come to dinner at this Italian restaurant?’ and she said, ‘When?’ I said, ‘Well, how about in an hour?’ And I hadn’t talked to her in months. And, she showed up and broke all the rules.”

“I’d just come from work [onTheDays of Our Lives] and had no makeup on,” recalls Rinna. “So I guess I wasn’t playingthathard to get.”
