Talk about one impressive bounce back.

Bar Refaeli may have given birth to a daughter named Liv less than three weeks ago, but the Israeli beauty is already back in tip top shape. The new mom took to Instagram today to share a photo of herself swimming through some beautiful blue water, and she looks more fit than ever. In the snap, the 31-year-old supermodel wears a black two-piece swimsuit as she glides through the waves. Her hair glistens as it reflects the sun in the image, which she simply captioned: "Crystal clear."

The baby girl is the first child for Refaeli and her husband, 41-year-old businessman Adi Ezra, who were married in Israel in September of last year. Last week, the Victoria's Secret model posted a 'gram of a glass of wine along with a tiny baby bottle, a clear pacifier, and a baby monitor, hinting that her new bundle of joy had arrived.

We can't wait to meet the little cutie.
