Sarah Michelle Gellar and Freddie Prinze Jr. just celebrated their 15th wedding anniversary, and they’re forever #relationshipgoals

We love celebrating relationship milestones. We can barely believe that Sarah Michelle Gellar and Freddie Prinze Jr. have been married for 15 years! Yesterday, Sarah Michelle Gellar posted a sweet Instagram slideshow to celebrate their wedding anniversary. And oh boy, the flashbacks are good.

The slideshow starts with a picture from their wedding back in 2002. It continues with more pictures of the couple, one from each year leading up until today. All together now: awwwwwww.

Gellar captioned the post with an adorable message to her hubby.

"My husband thinks I'm crazy, but I'm not the one who married me.#happyanniversary @realfreddieprinze 15 years!!"

Aww. We want a Sarah Michelle Gellar and Freddie Prinze Jr. kind of love!

The couple met on the set of the 1997 thriller I Know What You Did Last Summer. They started dating in 2000, married in 2002, and have two children together. Their 7-year-old daughter Charlotte Grace is Gellar’s twin! And 5-year-old Rocky James is equally as cute.

In a 2016 interview with People, the actress shared the secret to their long-lasting love.

"Take the 10 minutes – put the phone down. Have a cup of coffee together. Walk the dog at the end of the night. Read a story with your kids," she said. "Make the most of the time that you have. We are all pulled in so many directions, so make sure that, whichever one you are focusing on, you’re present."

It’s great to see a high-profile couple last so long in Hollywood. It’s hard to focus on the present and not be distracted by everything even when you aren’t famous, so we can only imagine how much harder it is for these two. Congratulations on 15 years, and cheers to 15 more!
