Hilary Duff Celebrates 3-Year Anniversary With Sweet Photos of Husband and Kids

The actress is 'over the top grateful' for her relationship.

Hilary Duff and her husband, Matthew Koma, are celebrating three years of marriage! 

The How I Met Your Father star, 35, took to Instagram on Wednesday, Dec 21. to commemorate the day she and Koma, 35, said "I do."

The first photo in the celebratory post captured the couple on their wedding day, walking back down the aisle after reading their vows.

Other photos showed snippets of Duff and Koma's relationship throughout the last few years, including shots from the gender reveal party for their daughter and other adorable moments with her family. 

Duff and Koma have two daughters, Mae James, 1, and Banks Violet, 4. The actress also shares a 10-year-old son, Luca, with her ex-husband, Mike Comrie.

"Matthew. I love you so much. Happy 3 years! I don’t know if you knew what you were getting into or that you weren’t going to sleep or sit down for the next 5-10 years but I think for the most part you’re pretty happy about it," she joked.

"Our life is so full and I’m over the top grateful for the guy that I got to do all this madness with," she wrote as she closed out the caption.

Fellow Hollywood friends took to the comments to congratulate the duo on three years of marriage, including Ashley Tisdale, who wrote, "Happy anniversary!!"

Mandy Moore also chimed in, writing, "You two are the best!! Happy Anniversary!!! ❤️❤️"

Koma also took a moment to share an anniversary post (and crack a few silly jokes). 

"We crushed 3 years @hilaryduff 🧡Anyone who says marriage is easy hasn’t been married, or is raging slightly too high a microdose. But the work is the best part. The beauty truly is in going deeper with someone than you’ve ever been before and navigating an invisible map that only the two of you can trek. The hard stuff makes the great stuff even greater, he wrote. "Thank you ba for loving me. I know that isn’t always easy."

Koma continued: "Thank you for listening to every version of Springsteen doing Santa Clause Is Coming To Town this time of year and pretending you know what I mean when I scream 'Clarance.' Thank you for letting me keep 6 beverages on my nightstand. Thank you for traveling to see Dawes with me in foreign countries. Thank you for raising our very cute and very unstable three kids. Thank you for being so hot and letting me do things to the body. It’s so sick."

He ended his caption with a joke about his wife leaving him for Harry Styles or The 1975's Matty Healy, "When you leave me for Harry, I’ll totally understand and I hope our kids get his fashion sense and that he loves going to sleep at 6pm as much as you. You’re not allowed to look at pictures of Matt Healy tho."

Happy anniversary to these two love birds!
