Freddie Prinze, Jr. & Sarah Michelle Gellar’s Anniversary Tweets Are Too Cute

Who knew that starring in a teen slasher flick could be the beginning of a beautifully enduring relationship? Freddie Prinze, Jr. and Sarah Michelle Gellar met on the set of I Know What You Did Last Summer back in the late 90s — and from that point on they've been inseparable. They were engaged in 2001, then married in 2002 on a beach in Mexico. The groom may or may not have worn shoes at the ceremony, but they both were definitely clad in all-white ensembles. (See evidence below.) And this week, the happy couple — who are now parents to two kiddos — celebrate 13 years together. The world got a sneak peek at their feelings for one another through social media. Spoiler: They are adorable. First, Sarah Michelle posted this pic to her Instagram.

Did you get a load of that sweet caption? She also shared the photo via her Twitter, where Freddie commented back.

Congrats to these two — in a summer where breakups seem to be running rampant, it's heartwarming to know one of our fave couples is still in it to win it.
