It looks like some of the entertainment world's finest got into the Halloween spirit in recent days judging from all of the costume pics that have been showcased on Twitter.

Diddy did Prince proud in a purple velvet cape and pants.  Television talk show host Ricki Lake was rocking a sexy costume that "Cher approved" and Paris Hilton made a lackluster attempt at Honey Boo Boo.

Nicole Richie and Ivanka Trump showed off their daughters while LeAnn Rimes and Eddie Cibrian were rocking Danny and Sandy of Grease fame.

Victoria Justice went historical -- uploading a photo collage of her Lincoln poses.  Our favorite Nicki Minaj impersonator turned out to be Miley Cyrus.

'Idol' host Ryan Seacrest and girlfriend Julianne Hough totally nailed notorious outlaws Bonnie & Clyde.

Ellen DeGeneres was a dead ringer, sorta, for Sofia Vergara and Weight Watcher spokeswoman Jessica Simpson showed off her slimmer body in a Scottish warrior maiden get-up.

A contingent of New York City celebs hit Bette Midler's annual charity fundraiser.  Braving the post-Sandy chaos on the East Coast were Debra Messing, Michael Kors, Lance LePere, Debbie Harry and Dita Von Tesse.

Hosting a gig at Planet Hollywood was the always lovely Jenny McCarthy, who donned a sexy catwoman get-up for the occasion.
