Jessica Simpson is the cover girl for Weight Watchers magazine's January/February issue!

The 32-year-old songstress, now pregnant with her second baby, chatted with the mag about her addiction to smoothies and how she stayed fit while filming Fashion Star. Jess told WW:

    “I’m crazy about smoothies, so I bring fruit chopped up and ready to go. That way, I can sip the same smoothie all morning long between takes. If it thins out, I put it back in the blender with crushed ice for a few minutes.”

Earlier this week, Weight Watchers announced that Jessica will not continue their program throughout her pregnancy, however once she gives birth, their partnership will continue.

Jess certainly has that pregnancy glow!
