Bar Refaeli - Lead

Bar Refaeli is keeping the pregnancy pictures coming. The Israeli model took to Instagram today to share her latest baby bump-baring swimsuit snap, and it's her most gorgeous one yet.

In the black-and-white 'gram, the mother-to-be in cute bandeau bikini top and coordinating side-tie bottoms as she lounges on a pillow floatie in the pool. The 31-year-old completed her summer-ready ensemble with a straw fedora and a pair of chic sunnies. And while Refaeli may look incredible in each and every single one of her maternity photos, it seems as she's ready for her first child to arrive. "You can come out now .. I'm ready. And heavy," she captioned the stunning image.

Since announcing her pregnancy back in December, Refaeli hasn't been shy about showing off her growing baby bump on Instagram—the expectant star has shared 'grams of herself wearing everything from cute workout geat to flowing maxi dresses.
