Bruce Willis and his wife Emma Heming Willis are celebrating a special day: their 12th wedding anniversary.

On Sunday, Heming, 42, captioned a photo on social media of herself snuggling into Willis', 66, neck. "Boy I sure do love this guy to the moon and back!" she wrote. 

"Even though there’s been times I would have loved to take him to the moon, drop him off, and come back solo! 🌚🤣 That’s what 12 years of marriage looks like, right?" Heming added. 

"We’ve had our fair share of floating-on-air ups and disheartening downs. But he is my person," the model continued. "There’s no one I would want to go through this crazy thing called marriage with than with him."
