Celebrities have been spotted out and about for the last week in Halloween costumes – from angels and devils to fellow celebrities. Now that Halloween is officially here, it’s time to list off some of the best celeb costumes.

Chris Colfer’s sexy R2D2 definitely deserves credit for sheer creativity. “This year for Halloween I decided to go as a character whose sex appeal is always ignored,” the Glee star wrote on Instagram. “I'm Sexy R2D2!”

Colfer’s fellow Glee star, Chord Overstreet decided to go as Charlie Hunnam’s Sons of Anarchy character Jax, proving he’s somewhat of a doppelganger for the British actor.

A top couples costume for this year, barring Isla Fisher and Sacha Baron Cohen’s odd getups, was Fergie and husband Josh Duhamel’s Elvira balding sidekick.

Nicole Richie paired up with much taller male friend to be the stars of the movie Twins. “Happy Halloween from your favorite #TWINS Arnold Schwarzenegger & Danny Devito,” Richie wrote on Instagram.

Miley Cyrus, the subject of many others’ Halloween costumes (including Paris Hilton), deciped to don a purple wig and dress up as Lil’ Kim.

TV host and comedian Ellen DeGeneres decided to dress up as a rapper as well – choosing Nicki MInaj. DeGeneres donned a replica of the underboob-exposing outfit the artist wore on her show earlier this month.

Today show hosts Matt Lauer and Willie Geist dressed up as Pamela Anderson and David Hasselhoff, repectively. Here they are posing alongside Baywatch star Carmen Elektra.

Check out Naya Rivera, Adam Brody, Paris Hilton, Vanessa Hudgens and Fisher and Cohen in their Halloween costumes in Uinterview's Celebrity Halloween Costumes Slideshow.
