Miley, Beyonce, Ellen DeGeneres: Who's Winning Halloween?

Vote on which celeb -- from Amber Rose to Blue Ivy -- is the true champ of Halloween.

Halloween is in full swing and so far, celebrities have brought out all the stops dressing in costumes that are sexy, creative and downright frightening.

In a snap from her Instagram, Miley Cyrus rang in Halloween by transforming into one of her favorite rappers, Lil' Kim, sporting her infamous 1999 Video Music Awards ensemble, which earned her a seal of approval from the Queen Bee herself.

Another artist paying homage this Halloween was Fabolous who was a spot-on replica of Michael Jackson from his "Thriller" video, complete with zombie make-up and red leather jacket.

Ellen DeGeneres also got in on the action, replicating Nicki Minaj's underboob outfit that she wore during her appearance on her show last month. The whole look prompted Nicki to tweet on Wednesday, "I didn't know Ellen could get any sexier."

Newlyweds Wiz Khalifa and Amber Rose opted out of matching looks. Instead Wiz sported a costume from the cult classic, "The Warriors," while Amber went for a Marie Antoinette costume. Before they hit the party scene, the couple shared an adorable photo of their son Sebastian dressed as a little lion.

Also dressing their little one for Halloween was Beyoncé, who posted an adorable photo on Instagram of her wearing a halo and a pair of angel wings while holding Blue Ivy, who appears to be dressed as a bumble bee.
