Vanessa Lachey may have been trying to keep her bump private by dressing in a long, loose-fitting maxi dress on Saturday, but the wind had other plans! A gust of Malibu breeze had the mom-to-be clutching at her maternity dress to prevent a wardrobe mishap.

Vanessa Lachey, who recently revealed she and husband Nick Lachey are expecting a boy, stopped into California eatery Moonshadows, as well as Neiman Marcus during her outing.

The 31-year-old recently turned to her fans for help planning their baby shower, writing, “Nick and I love going through these life experiences together, and we are thinking of doing a Jack & Jill baby shower. I think it will be AMAZING! Share your ideas!”
