sunglasses January Jones beach pregnant dog

January Jones looked adorable in a dark blue maxi dress and green bandanna tied just below her growing baby belly, as she took a leisurely stroll with her dog down Malibu beach, on Sunday.

The mommy-to-be will begin shooting Mad Men season 5 today, but thankfully the show's creator, Matthew Weiner, has got a plan to hide that baby bump.

The X Men: First Class star will shoot her scenes with the help of a body double for now, and return for re-shoots after the baby is born in the fall.
