While Camila Alves' pregnant belly keeps growing, her hubby Matthew McConaughey is withering away as the pair grabbed a bite to eat in New York City on Friday (August 31).

Taking their impeccably dressed children by the hand, the Brazilian-American model lead the way in a stunning floor length black maxi while a few steps back her "Magic Mike" husband looked casual in jeans and a wrinkly button-up.

With baby number three on the way, the 30-year-old recently gave expecting mothers some fashion advice telling Us Weekly, "Do not be afraid to be sexy while you're pregnant. I'm learning that on my third pregnancy. I'm like, "Oh wow, you don't have to wear just flowing t hings."'

As for Matthew's rapidly declining weight, the 42-year-old actor is preparing for his role in "The Dallas Buyer's Club" where he plays a frail HIV patient determined to defy all odds after being told to "go home and die."
