Prediction: You Will Steal Kourtney Kardashian's Birthday Glam

Kourtney Kardashian just turned 37-year's-old, and spent the big day chilling out in Iceland with her family, not to mention her glam squad. The mother-of-three was treated to a beauty blowout courtesty of Justine Marjan (editorial director of Mane Addicts) and Kim Kardashian's makeup guru, Mario Dedivanovic.

Marjan styled Kourtney's hair in what appear to be simple, elongated S-waves, while Dedivanovic created what he calls a "semi-smokey cat eye." The results? See for yourself.

Praying that we all look this good at 37.
