Irina Shayk and Bradley Cooper Share the Sexiest Bikini Selfie of All Time

Bradley Cooper and Irina Shayk have made their red carpet debut, but as a celebrity couple they've kept things relatively private, especially on social media. But oh, how things change with just one Instagram. Irina recently posted a snap of she and her beau sitting in what appears to be a pool or hot tub. Then again, we care less about the temperature of the water and way more about the design of the supermodel's smoking one-piece.

Of course, the strappy number with a plunging neckline may not be the easiest silhouette to pull off, but there's no denying it's trendy and flatters Irina's figure. Since we're also into the teal shade of her swimsuit, we're shopping for alternatives that are just as sexy but maybe a smidgen more modest. Read on to see Ms. Shayk's 'gram, then decide how low you're willing to go before the Summer hits.
