"Happy 22nd birthday to @karliekloss, who is made out of 100% sunshine," the pop star wrote alongside a sweet outdoorsy shot of the birthday girl.
Kloss and Swift have been tight since the singer performed at the Victoria's Secret Fashion Show last fall. Earlier this week the besties were spied getting their groove on at an Ingrid Michaelson concert. And if we know Tay, she's no doubt baked up some delicious Ina Garten-approved birthday cake for her gal pal. Or maybe Kloss is getting her own Drake needlepoint?
Have fun with your celebrations, ladies. We'll be living vicariously through your Instas.
