To celebrate Kourtney Kardashian's 36th birthday today, we're taking a look back at her most memorable maternity outfits. And believe us, we were spoiled for choice. The reality star-turned-designer is mom of three kids with longtime boyfriend Scott Disick: 5-year-old Mason, 2-year-old Penelope, and their most recent arrival, Aston Reign. Kardashian clearly has pregnancy dressing down to an art: The star never fails to make a statement when stepping out, whether she rocks a breezy Cameo shift, a body-hugging lace jumpsuit, or an empire-waist maxi dress. Thanks for the inspiration, Kourtney! See the birthday girl's best maternity style moment in our gallery below. PHOTOS: Kourtney Kardashian's Maternity Style Gallery
