Although it feels like it was just yesterday that they tied the knot, lovebirds Catherine Zeta-Jones, 46, and Michael Douglas, 71, have already reached a major milestone. Despite their fair share of rough patches, the Hollywood power couple is still going strong, and celebrated their 15th wedding anniversary on Wednesday. Oh how time flies when you're having fun—and making movies!

And because nothing's official until it's on social media these days, Zeta-Jones marked the occasion with an adorable photo of herself with her husband on Instagram.

"Happy Anniversary dearest Michael! Loving our life together, here's to the next 15!" Zeta-Jones captioned the snap and included a heart emoji. The sweet black-and-white image shows Zeta-Jones beaming while receiving a tender forehead smooch from Douglas.

Congrats to the couple!
