How wild does a grown up Halloween party get for the police to be called???  Turns out the neighbours weren’t too happy with the noise level.  The police stopped by at 1 a.m. and asked them to take the party inside.  That sounds like fun!!!! 

Celebs in attendance and dressed in Halloween garb:

• Kate Hudson was a 1960′s flight attendant
• Courtney Cox dressed as a witch
• David Arquette as a warlock
• Winona Ryder as a mouse
• Cindy Crawford went as Amy Winehouse (that’s hysterical).

The biggest hit of the party???  None other than Gerard Butler!!!  According to a source:

“All the girls at the party were lining up to talk to Gerard. He left with two very sexy vampires.”

Given that Jennifer Aniston’s best pal, Courtney Cox was there, I’m sure this information will get back to her.  Maybe they just have a FWB arrangement?  And to Gerry’s fans:  don’t hurt the messenger

Update:  According to PageSix, Gerard Butler was dressed as a cowboy.  The expression Ride ‘em Cowboy seems pretty fitting in this case, no?
