This is so divine! Mariah Carey is Imperfect Angel attended her Halloween party at M2 Club in New York!

Katie Price and her boyfriend Alex Reid at the Bloodlust Ball held at the Hampton Court House in London, UK.

Kelly Osbourne and her fiance Luke Worrall at the Halloween Party at the Playboy mansion in Los Angeles, Ca. There’s nothing better in this world than fried eggs with crunchy bacon strips… Luv it!

Gwen Stefani and Zuma trick-or-treating in Los Angeles, CA. Um, can’t quite put a finger on Gwen’s character. Wendy’s perhaps? Gwen’s husband, Gavin Rossdale, was easy to figure out. He’s the Invisible Man!

It’s good to be seen, right?

L@@K!!! Cleopatra riding a batboy! Actually, this is Liv Tyler and son Milo heading out to trick-or-treat.

Puzzled about Brooke Shields’ costume too.

This is awesome! If these guys wanted to rob a bank, they’re good to go. Need some guns though, Mr. Soprano, DUH, Homer.

Hey, look at these two fairies! Paris Hilton with her tooth fairy boyfriend Doug Reinhardt attended Heidi Klum and Seal’s Halloween costume party in Los Angeles, CA. Heidi Klum used to host her annual Halloween parties in New York, memba? 

Take two! So, who makes a better Dorothy, Paris or Doug? (this is photo composite). FYI: Jordin Sparks sported Dorothy look as well. We don’t have the picture to show though.

Hey, pirates! Christina Aguilera with her son Max Bratmam trick-or-treat in LA.

LOS ANGELES, CA — Britney Spears is back and loving it! Dressed as a witch Britney was having a good time while trick-or-treating with her kids and friends on Halloween night, and we have pictures straight from the horse’s mouth! It’s a good thing Britney dishes on her official web site, thereby discouraging paparazzi from stalking her 24/7. Perhaps it’s best for Britney to take a break from too much attention to better prepare for her upcoming world tour. Enlarge the thumbnails below!

NEW YORK — Who is this Cleopatra making an appearance on “The Martha Stewart Show” during Martha’s Halloween Spectacular? Watch the video segment below to find out! XOXO (hint hint).
