Karlie Kloss and Taylor Swift may have busy schedules that keep them apart, but that didn’t stop Kloss from celebrating her pal on social media on her birthday.

The supermodel and close friend to the Reputation singer posted a sweet throwback selfie of the duo on Instagram in honor of Swift’s 28th birthday today.

“Happy happy birthday @taylorswift! 💫” Kloss captioned the beachside shot.

The throwback selfie appears to be a behind-the-scenes look at the two stars’ famous March 2015 Vogue cover shoot, which they graced together in honor of the fashion magazine’s Power Issue.

The spread, shot by photographer Mikael Jansson, followed Swift and Kloss on a road trip in Big Sur while giving readers insight into their highly publicized friendship, which started soon after the two met backstage at the 2013 Victoria’s Secret Fashion Show.

“People had been telling us for years we needed to meet,” Swift said. “I remember makeup artists and hair people going, ‘Doesn’t she remind you of Karlie? God, she and Karlie would be best friends. They’re the same. Karlie’s such a good girl. She brings us cookies every time we do a shoot.’ ”

Fellow VS model Lily Aldridge was the person who ultimately introduced Kloss and Swift. “And we were just like, ‘You. My friend. Now,’ ” said Swift.

Despite their superstar statuses, the two claim their friendship is as normal as it gets. “We’re both normal people,” said Kloss.

“We’re real girls,” Swift added. “The fun thing about my friends is that they don’t necessarily know a lot about what I do business-wise. I’m not the person who grabs the guitar at a party and wants all the attention. I have attention on me enough, so I want my friends to just like me because we have things in common rather than me sitting in a corner being like, ‘Listen to this song that I wrote about my life!’”

While Kloss’ name appeared to be absent from Taylor’s “Squad” shirt in the “Look What You Made Me Do” music video, generating buzz of a rift between the BFFs, the pair have seemed to maintain their friendship and Kloss was very happy for Swift when she took home the Song of the Year Award at the 2017 CMA Awards for writing Little Big Town’s “Better Man.”
