Getting married and staying married is already hard enough, when both people are celebrities; it becomes 100x more difficult to make it work.
Speaking in the new issue of Elle magazine, Gwyneth said: "Sometimes it’s hard being with someone for a long time. We go through periods that aren’t all rosy. I always say, life is long and you never know what’s going to happen."
Gwyneth and Chris are notoriously private about the relationship. They’re never photographed together, they don’t attend each other’s work events and they hardly ever speak about each other. So naturally that’s resulted in a ton of breakup rumors over the years.
But she insists if they were ever to split, no one would know the details because it would never get as ugly as some celeb splits.
She told Elle magazine: "If, God forbid, we were ever not to be together, I respect him so much as the father of my children.
"I made such a good choice. He’s such a good dad. You can never be relaxed or smug and think, 'I’ve got this thing.'
"That’s also part of it: keeping yourself on your toes. I’m not going to take this for granted."
They’ve managed to stay married for seven years, which is like a lifetime in Hollywood so clearly they’re doing something right!
