Sarah Michelle Gellar at her daughter Charlotte’s school today with ears and a skull shirt.

Christina Aguilera took her son Max trick-or-treating. Is that how big he is now?

Gwen Stefani and Zuma were out for Halloween in London having just arrived from Los Angeles. I love this kid. He’s always so happy and naughty.

Sandra Bullock picked up little Louis from school. He seems exhausted from all the Halloween-ing.

And Sarah Jessica Parker returned to her place in Manhattan after Sandy.

Be safe out there tonight!
