Kourtney Kardashian has opened up in the past about how much she enjoys being pregnant and so it was apt that she chose to mark younger sister Kim Kardashian's birthday on Monday with a sweet throwback photo of the pair, which had been taken when she was expecting her son Mason – now nine. In the picture, the pair were sitting on the sofa wearing matching dresses, while Kourtney was holding her baby bump. "Nine months pregnant @kimkardashian," the mother-of-three captioned the photo. Kourtney was the first of the Kardashian clang to have a baby and went on to welcome daughter Penelope, seven, and son Reign, four.

The oldest Kardashian sister also chose to share another throwback photo of the pair to mark Kim's birthday, which was taken in the mid-nineties at a restaurant. "Happy birthday Kimberly Noel Kardashian West! I love you forever," she wrote in the caption. In the picture, Kim was wearing a pink cardigan and a pearl necklace, while Kourtney rocked blonde highlights and a white polo shirt. Fans adored seeing the unseen picture, in particular their fashion choices. "Omg the cardigan and pearls," one wrote, while another mistook Kourtney for Khloe Kardashian: "I for real thought that was @khloekardashian on the left!" they wrote.
