Now I know it's tough to take any marriage advice from a celebrity couple -- especially since most don't stay together long enough to even give advice.

Kevin Bacon and Kyra Sedgwick, however, have been longtime residents of Sharon, Connecticut, and have managed to stay married now for 31 years. So what's their secret? Both actually gave their best advice in a recent interview at

For both Bacon and Sedgwick, staying active is a shared value, and just one of the many principles on which they've built their 31-year marriage. One of the topics Kevin spoke to Glamour about was knowing when it's your turn to step up:

Kyra's made a lot more sacrifices than I’ve made. She felt really strongly that, when we started to have children, she needed to be there for them. In many cases, because of the kids, she would make decisions career wise that weren’t the best for her career. Then when The Closer came along I said, listen, I’ll stay with the kids. In this case, this was the first time in our lives I said, I’ll stay home, I won’t take anything. Both of us knew that I said that, but in the back of my mind I was like, I hope I don’t get offered anything great. But for the most part, she’s the one that did the sacrificing.

As far as Sedgwick is concerned, her advice is don't hit below the belt, especially when you disagree with your partner. Here's what she had to say about that to

I think the biggest fight we ever had was when I wanted to move back to Manhattan and he wanted to stay in Connecticut. That was a big one, and it lasted a long time. But we don’t hit below the belt. Neither of us has the constitution for that, and I mean that in a good way. I don’t think we could dish it out or take it, frankly. Ultimately, I don’t want to fight and he doesn’t either.

Some of the couples' other advice for a long and happy relationship include "know when to step up," "be each other's mirror" and "make the bed." As Bacon says:

We don’t start with No. No, you can’t do that. You can’t go away. You can’t do that job. It’s kind of the opposite. If something comes up, we mostly say, This is our lives; we’ll make it work.
