Happy 45th birthday to one of the OG Kardashian sisters, Kourtney! Can you believe it's already been 45 years since your iconic birth on April 18th? You've truly aged like a fine wine, only getting better with time. Wishing you a year filled with love, happiness, and of course, drama (because let's be real, it wouldn't be a true Kardashian celebration without a little bit of chaos). Cheers to another year of being fabulous at 45!
