Mariah Carey & Nick Cannon arrived at a Halloween Party on the back of a fire engine… That’s hot.  Mariah apparently couldn’t decide what to dress as, so she went from fire girl to Famous Amos cookie girl over the course of the night… either that or she has a twin?

Tons of pictures of celebs at various parties/trick or treating… Check them out – just click on the first picture and then scroll through them.  Kimberly Stewart attempted to go as Britney Spears… so lame.  As if Kim is anyone to make fun of anyone else.  She looks more like Katie Holmes than Britney anyway!!

Gwen Stefani and Gavin Rossdale played on the beach with Kingston – and Kate Beckinsale and her daughter Lily.  Look at their bounce castle, that thing is awesome!  My boyfriend’s sister and I were just talking about investing in one the other day… how fun would one of those be for the kids at parties!

Kate Beckinsale made a super hot Devil the other night… Wouldn’t it be great to be able to splurge like crazy on a Halloween costume?? 

Kate Beckinsale took her daughter Lily to get their nails done… super cute!!

Or is it grab-ass?  Grab ass two words?  I don’t know, but how cute.  Kate Beckinsale and her husband Len Wiseman dancing at the Die Hard 4 after party in London.

Kate Beckinsale is finally getting some attention from her husband Len Wiseman… a few weeks ago she was complaining about the lack of sex because he’s so busy with work, but they found some time to go shopping together!

Kate Beckinsale on the set of Winged Creatures… with her thong hanging out ;)

I don’t think I really like her has a blonde, she’s so fair, I think she looks much better with brown hair.
