Fans know what Sarah Michelle Gellar and Freddie Prinze Jr. did this summer—they went on a family vacation to Italy. 

The I Know What You Did Last Summer co-stars recently took a trip to Florence with their daughter Charlotte, 13, and son Rocky, 10. As Sarah announced on Instagram Stories July 18, "Italy we have arrived."  

The actress proceeded to give followers a few glimpses into their getaway, posting pictures of the stunning views and noting they were "off to a private dinner." She also shared a snapshot of her and Freddie smiling with their children, captioning the image, "La mia famiglia a Firenze Italia."

Sarah—who covered Charlotte and Rocky's faces in the photo with heart emojis—and Freddie don't often post pictures of their kids on social media as they're protective of their privacy. In fact, the Buffy the Vampire Slayer alum previously noted they don't allow their children to have social media accounts.

"Our rules are probably stricter than most," she told Yahoo Life's parenting series So Mini Ways in October. "Our kids don't have social media. They're allowed to look sometimes when it's our phones. Sometimes, our kids will be like 'you guys are the strictest household!' But I say, 'yes, but everyone still wants to come here!'"

As for the reason behind the rule, Sarah said she tried to explain to her kids the lasting impact posting on social media can have by likening it to getting a Paw Patrol face tattoo at age 5.   

"Because at that age, there's nothing better than Paw Patrol," she continued. "And now you're 10 and [13], and you still have these tattoos on your face and it's not even who you are anymore. That's a very hard concept for young kids to grasp."

And ultimately, the Cruel Intentions star feels that having her kids follow certain rules is what's best for them. 

"I believe kids need to know what their limitations are, and they actually thrive in that environment," she told the outlet. "We're not mean, we're not unnecessarily strict, but we have rules. And the same way I abide by my code of rules, I expect the same from our children."

To see some of the cutest photos Sarah and Freddie have shared of themselves over the years, keep scrolling.

In January 2019, Sarah Michelle Gellar and Freddie Prinze Jr. had a double date with Shannen Doherty and her now-ex Kurt Iswarienko.

"No mistletoe, no problem," the mom of two wrote on this December 2018 kissy photo.

In 2018, the lovebirds took their Halloween costumes to the next level by dressing up as characters from The Royal Tenenbaums. 

It doesn't matter what these two do, as long as they're together they are having a good time.

"If you were ice cream, you would be my favorite flavor," Gellar captioned this sweet snap in 2018.

"It's the freakin weekend, baby I'm about to have me some fun," Gellar wrote on this cheeky post in March of 2018.

In December 2017, the cute couple had some fun at an engagement party thanks to photo booth props.

Gellar channeled her inner Molly Ringwald with her Andie costume from Pretty in Pink in 2017 while her husband nailed it as Duckie (played by Jon Cryer) from the film.

"The only time I don't mind giving up #independence lol," Gellar joked to her followers on the 4th of July in 2017.

The couple that snaps selfies together, stays together! 

Gellar's birthday message in 2017 to her bestie and husband was just the cutest. "Happy birthday @realfreddieprinze 'the happiest people don't have the best of everything, they just make the best of everything.'"

In January 2017, the pair celebrated National Spouse Day by taking this pic and it's too cute.

"Someone let me know who that red head was seen trick or treating with @realfreddieprinze ..." Gellar joked on Instagram while celebrating Halloween in 2016.

The Scooby-Doo stars soaked up the last bits of summer together in 2016 and clearly they enjoyed every minute together. 

The Buffy the Vampire Slayer alum couldn't help but gush about her husband after his cookbook came out.

"Finally out like the adults we are...to see #fantasticalbeastsandwheretofindthem," Gellar revealed while out on a date night in November 2016.

In October 2015, the duo posed with wrestling belts and tried to out muscle each other.

The bond between Gellar, Prinze and Selma Blair has lasted for three decades and we can't wait to see what they do during the next three.

The Back to the Kitchen author and his wife are often found in the kitchen whipping up delicious meals for their family. 

In this adorable throwback, Gellar revealed that the couple took this photo in Hawaii after they learned they were expecting their daughter Charlotte!

These two have had a lot of fun in their relationship, and the Foodstirs creator's Dirty 30 was no exception. 

This throwback snap is from when the happy couple had their first Thanksgiving together and it's a total blast from the past.

The I Know What You Did Last Summer co-stars look like babies in this photo from a vacation way back before they had kids together.

We just love these two.

How happy do these two lovebirds look in this sweet photo from their honeymoon back in 2002?!

Clearly this pair was a match made in smiley heaven.

"I love you not only for what you are, but for what I am when I am with you," Gellar shared on one of her past wedding anniversaries. "I love you not only for what you have made of yourself, but for what you are making of me."
