Jessica Alba and Her Ribs Party in Miami

Jessica Alba spent her holiday weekend training for the Hot Actress Professional Water Football League (HAPWFL).

Oh, and not eating.

The Hollywood Gossip is appalled and frightened by these pictures. We know Alba and Kate Bosworth both enjoy walking dogs, but we didn't think The Fantastc Four star also shared Bosworth's passion for an empty plate at every meal.

Just look at that arm - or lack thereof. It would give a Nicole Richie limb a run for its anorexic money.

Look, Jess, we're not telling you to look like Rosie O'Donnell. But there's no need to impersonate a skeleton, either. Eat.
