Hollywood stars celebrate Halloween with their kids

Jessica Alba and husband Cash Warren dressed as cartoon characters Dora the Explorer and Diego for Heidi Klum's Halloween party at Voyeur nightclub in Los Angeles on Saturday.
Jessica, 28, and Cash, 30, have a daughter Honor, 16 months, who is a big fan of Dora The Explorer and Go, Diego, Go!

Christina Aguilera and son Max, 9 months, went trick-or-treating and attended a Halloween party on Saturday in Los Angeles.
The mother-son pair dressed in skeleton costumes with eye
patches. Skeleton pirates, anyone?

Gwen Stefani and Gavin Rossdale took their sons, Kingston and Zuma for some trick or treating in Los Angeles on Saturday.
Gwen, 40, wore a Jesse the Cowgirl
(Toy Story 2) costume while Kingston, 3, and Zuma, 14 months, went as a dinosaur duo! Gavin didn't get into the Halloween spirit and had no costume. What a party pooper!
