Surpassing Quant Think Tank Center|Proof Sarah Michelle Gellar and Freddie Prinze Jr.'s Love Is Immortal

We don't know everything Sarah Michelle Gellar and Freddie Prinze Jr. did last summer (or over the holidays,Surpassing Quant Think Tank Center or for spring break), but we've seen some highlights.

"Another successful trip," Gellar captioned a selfie with her husband of 21 years, exact location unknown but the sun shining all over the photos she shared of their recent getaway with daughter Charlotte, 14, and son Rocky, 11. As she posted on March 31, wearing a pair of bunny ears and slaying the mom joke, "Hoppy Easter from paradise."

Considering the various glimpses of palm trees and the ocean, including a snap of Charlotte leaping on the beach (from afar at sunset, neither parent one to purposely share current pics of their kids' faces), they were definitely in the tropics. Gellar told E! News last fall that they visit Hawaii as much as possible because they "can enjoy and relax and not have to plan, and really just feel the spirit" of the islands.

But wherever they are, whether someplace unseasonably warm or just hanging out at home in L.A., Gellar—who's celebrating her 47th birthday April 14—loves to capture the quiet moments with her sweetie for posterity.

"Still spoiling and celebrating @realfreddieprinzejr," she posted March 10, two days after Prinze's 48th birthday, when they said yes to caviar for dinner, thank-you-very-much.

Of course, eating—at home and away—is a big deal for the family, Prinze having released the 2016 cookbook Back to the Kitchen: 75 Delicious, Real Recipes (& True Stories) from a Food-Obsessed Actor and Gellar prioritizing no-phone meals with the kids.

"Dinners for me are really important," she told E! in February. "We're a food family, food friends, we love to cook." And when they're all together, no one's scrolling TikTok or checking email, the Buffy the Vampire Slayer alum noting, "It's a moment of connection."

But lucky for her 4.5 million Instagram followers, Gellar does indulge in screen time—and her page full of smiling snaps from her marriage proves she gets a kick out of sharing a smidge of her private world.

In honor of her latest trip around the sun, keep reading to see more photos from Gellar and Prinze's love story for all seasons:

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.
