Bar Refaeli took to Instagram on Friday to share a photo of herself getting some sun in a bikini. The Israeli model, who is expecting her first child with husband Adi Ezra, put her growing baby bump on display, writing, "My girl craved some vitamin D. #5months." Bar and Adi tied the knot in September, and just a few months later, the Sports Illustrated cover girl and former flame to Leonardo DiCaprio announced that she was pregnant — and judging from her photo caption, it looks like Bar will be welcoming a daughter!
