It’s Halloween, that wonderful day when we get to consume large amounts of candy while flicking through Twitpics of people in Halloween costumes. And not just any people: famous people. Or, if we’re especially lucky, famous people attempting to look like other famous people.

Here are some of the more enjoyable celebrity Halloween costumes that have been shared on Twitter within the past 24 hours. No doubt, there are more to come.

Perhaps the most widely disseminated celebrity Halloween costume of the day is this one of Miley Cyrus as Nicki Minaj. Minaj apparently intends to bring this full circle and dress up as Cyrus as well, according to the Hollywood Reporter, but no pictures of Nicki looking like Miley at the VMAs have surfaced yet.

Mariah Carey, BFF of Minaj, naturally tweeted out adorable photos of her twins in costume.

Happy Halloween everybody! We have festive new pics with #DemBabies at Halloween edition!…

Not to be outdone in the cute baby department, ladies and gentlemen, Jessica Simpson and her family.

Happy Halloween!!!

Also generating a lot of kudos on the Internet: Patton Oswalt’s extremely impressive Doc Ock ensemble, created with an assist from Adam Savage of “Mythbusters.”

Mission accomplished. With a LOT of help from @donttrythis (MYTHBUSTERS’ Adam Savage). #Halloween #doctorockapus…

Nathan Filion opted to go as Captain Canada, who, apparently, is the North American superheroic brother of Captain America:

Having already gone to a Halloween party over the weekend as “The Llaminator” (that would be a llama assassin, obviously), Chris Colfer topped himself today the only way he knew how: by going as Marie Antoinette’s guillotine.

Here’s a better Halloween picture of me and Marie courtesy of @adammshankman. Everyone stay safe tonight!

According to a tweet from a Variety writer, Disney CEO Bob Iger did the obvious thing, given recent events: He showed up at the company Halloween party dressed as Lord Vader.

I am not sure who is wearing this costume, but it was endorsed by Jenna Fischer of “The Office.” And for good reason.

Quite possibly the best parent/baby Halloween costume ever!…

No celebrity Halloween costume round-up would be complete without photos of famous people’s pets.

Therefore, here’s one of Amber Riley’s canine companions.

Chewie and Mylo about to go trick-or-treating! I miss my babies :(…

And here’s another of Sid Vicious, the pup that belongs to John Taylor of Duran Duran and, courtesy of this costume, is finally living up to the name “vicious.”
