Neil Patrick Harris's Stylish Twins Are Too Cute—See Their Sweetest Moments

Harper and Gideon joined their dads at the 2017 Saks Fifth Avenue & Disney Once Upon a Holiday Window Unveiling in N.Y.C. and they sure looked cozy while doing it. What a fun way to kick off the holiday season.

Harper and Gideon looked posh in their preppiest summer wear at the 2017 Veuve Clicquot Polo Classic. 

"Happy #dayafternationalsiblingsday to my favorite two twins," NPH captioned this adorable photo of the twins prepping for Easter in the kitchen.

Harper and Gideon didn't look all too pleased after their house got trashed by Leprechauns. "Gideon and Harper were far from pleased by all this Irish mischief. Toilet paper everywhere. Cushions upended. Dining room chairs in a pile. iPad taped to the chandelier. Whiskey drank," Harris wrote.

The siblings celebrated V-Day in style wearing matching heart tees and glasses. "Happy Valentine's Day from these two bundles of love! #cupids," NPH wrote.

The kids celebrated their snow day by enjoying a couple snow cones, thanks to dad David Burtka.

"Nothing like a Disney breakfast!!" Burtka captioned this silly pic.

"Introducing the newest member of our family GIDGET!," Burtka captioned this adorable collage of the newly adopted pup in November 2016. "Thank you @animalleague and @bethostern #getyourrescueon."

"First football game for these two (not quite) giants. Go Big Blue! #nygiants," NPH captioned this smiley photo of his twins at their first New York Giants game in November 2016. Those are some pretty great seats to watch your team win (28 to 23 against the Philadelphia Eagles)!

David Burtka posted this picture of Harper and her breakfast of choice in early November 2016, writing: "This is what my daughter asked for for breakfast... a plate of anchovies. What a strange child..." We must say, we agree—that's an odd pick, Harper. 

The blonde twosome look completely at peace meditating together on a rock—or, as dad Neil Patrick Harris puts it: “Meditation rocks.”

The charming twins encounter love and support at every turn, like while they’re feasting on a plate of shrimp.  

A daddy's girl through and through, Harper can't contain her excitement while dancing around with her loving fathers.

Clearly, the world's coolest 6-year-olds have a theatrical future ahead of them. 

The twins celebrate their first day of school with city kid attitude and adorable sunglasses. 

The Burtka-Harris clan celebrates Halloween like no other. In 2013, Harper and Gideon channeled Alice and the Rabbit from Alice in Wonderland, respectively, while their dads twinned as Tweedledee and Tweedledum.

Harper and Gideon don't need Halloween as an excuse to up their disguise game—any old day of the week is just fine for these two. 

The sweet brother and sister wrapped their arms lovingly around each other while admiring the serene water ahead.

The twins posed outside their home in glorious retro costumes—we hope they're enrolled in children's theater!

Rocking bold hues and colorful prints, the Burtka-Harris twins are ready to battle the elements—and pose for an L.L.Bean catalogue in the process.

Coordinating in seasonal yellow, the twins looks eager to bust into their Easter baskets' bounty. 

These classy six-year-olds are far from picky. Here they are enjoying a festive holiday dinner. 

The tots were all smiles in their fashionable 3D glasses, full pails of popcorn at the ready. 

Those little snowmen are bigger than the twins!
