Kris Jenner's eldest daughter and reality star, Kourtney Kardashian, is celebrating her birthday on Saturday. Commemorating the special day, Kris took to her official Instagram handle and dropped some unseen pictures of Kourtney on her social media handle. 

The album incorporates the birthday girl's photos - ranging from her childhood to her teen years, to her wedding, to some recent pictures of Kourtney. In one of the clicks, a heavily pregnant Kourtney was seen flaunting her baby bump. We could also see her smiling at the camera, posing with her little bundle of joy.
