One of Hollywood's cutest couples, Bruce Willis and his wife, Emma Heming, who just celebrated eight years of marriage, tell Closer Weekly — in its new issue, on stands now — that they look forward to many more years of love and laughter together.

"We have a great foundation," Emma told Closer at the annual Room to Grow spring charity benefit. "He makes me laugh."

For the English actress, 38, humor is a key factor to their marital success. "You’ve got to keep laughing because if you stop, you’re going to have some issues," she says.
