Is it just us, or are Chrissy Teigen and her belly getting cuter by the day? On Saturday the model and mother-to-be shared a photo on Instagram of her budding baby bump dressed for the high seas in a nautical navy bathing suit with a plunging halter neckline and a striped, vintage-inspired lower half (below). The co-host of Lip Sync Battle and FABLife, who seemed to be enjoying the unusually balmy winter weather, posed in front of a fireplace surrounded by tropical decor.

Teigen wore her stands pulled back and up into a massive bun on her head, a natural makeup look, and a coy smile.

Just last week, the maternity style icon and her husband, singer John Legend, announced their baby's sex, revealing on Instagram that they were expecting a little girl.
