Jessica Alba and Honor in Halloween Costumes Pictures

Jessica Alba and Honor were in costume after attending a Halloween party in Santa Monica yesterday. Honor was dressed up as Princess Jasmine while Jessica painted her face like a cat and topped off her outfit with an Ella Moss fur vest. Honor switched into her homemade Bubble Guppies dress for trick-or-treating later that night and dad Cash Warren got in on the fun in a Superman suit. Baby Haven was along for her first Halloween, though we didn't get a glimpse of her dressed-up look. There were lots of celebrity kids in costume over the past few days as Hollywood celebrated the spooky holiday, and next year there will be another famous baby to add to the mix since Jessica Simpson just announced her pregnancy!
