Celebs on Halloween

Of course celebrities like Halloween. Actors and actresses dress up for a living, and reality stars love the attention!  We spotted a slew of stars over the holiday weekend channeling their inner child in a variety of costumes.

"Girl Next Door" Kendra Wilkinson opted for a sexy mobster outfit, while Ciara looked freakish in a one-piece leather suit and spooky contact lenses.

Snooki wore a strange green ensemble and carried what looked like a pickle on a stick.

Christina Aguilera was a sexy cop, and Amanda Seyfriend wore a large, fluffy dog costume.

Check out the pics below!
