A blink of the eye, and before you know it, our beloved 2007 rookie, Irina Shayk, is all grown up! 

To celebrate the Russian model's 29th birthday, we're taking a little trip down memory lane. From Chile to Madagascar and beyond, Irina has traveled the world with our team, and we've rounded up some of our favorite shots from her eight (!) SI Swimsuit appearances. 

Happy birthday, Irina! Enjoy the end of your 20s—you already know how much we love you!
