Kailyn Lowry, 28, is glowing while preparing to welcome her fourth child to the world! The Teen Mom 2 star took to her Instagram Story to share a gorgeous photo of herself on June 2, in which she proudly held her almost 33-week baby bump while rocking a dark-colored bikini. She kept her bun in the oven safe with a white crocheted beach coverup dress, which featured fringed strings hanging down from a criss-cross section at her chest.
