Karlie Kloss Just Turned Taylor Swift's Favorite Age

The model has turned one of Swift's favorite ages: 22!

Birthday messages are in order for Karlie Kloss, impressive model-y type and doppleganger bestie of Taylor Swift. And the singer did just that with a wee lil Instagram ode to her friend-o extraordinaire in honor of her 22nd year on this earth.

Yes, Karlie Kloss is only 22 and no we had no idea, either. But that's the case Swifty here has made in the mini-message, and what she says goes. That's also how we know the secret to Kloss' prettiness and general cool-girl style: she's "made of 100% sunshine."

"Happy 22nd birthday to @karliekloss, who is made out of 100% sunshine," Swift said in the Insta-photo.

And if you need any guidance on what you need to know about being 22, Karlie, we're sure your gal Taylor can help you out on that front. Spoiler alert: It's going to be a good one!
