Jessie James Decker is having some fun on Instagram with a hilarious new post. Taking to the social media platform on Monday, the 32-year-old singer shared a two-part video of herself in the crystal clear, blue-green waters of the Dominican Republic. In the post, the mom-of-three shares a pair of contrasting videos -- one of her emerging from the ocean flaunting her bikini bod in a striped two-piece, while the other features her clumsily flailing and stumbling out of the water.
