TV Article Celebrity Halloween costumes: Miley Cyrus, Patton Oswalt & more By Hillary Busis Published on October 31, 2012 10:30PM EDT When Halloween falls in the middle of the week — and is celebrated the previous weekend — the holiday seems to last for days and days. That's fine by us, since it gives that many more opportunities to marvel at celebrity costumes. The meta trend seems especially big this year, with stars like Ellen DeGeneres, Emma Roberts, Glee's Chord Overstreet, and, er, that guy who was married to Avril Lavigne all dressing up as other famous people. Now Miley Cyrus has followed in those famous footsteps, showing off her take on Peg Bundy Nicki Minaj via her Twitter page. Check out Miley's getup — as well as several other decked-out boldfaced names — after the jump. https://twitter.com/MileyCyrus/status/263607535595036672/ In return, Nicki has said that she's going to dress up as Miley. It'd be even better if she went as Mileyas Justin Bieber. https://twitter.com/pattonoswalt/status/263421104536817664 Patton Oswalt as Doctor Octopus: best dad ever? https://twitter.com/NathanFillion/status/263731019667103744 Alberta native Nathan Fillion shows his national colors with a cheeky Captain Canada costume. https://twitter.com/Jon_Favreau/status/263703849683017728 Jon Favreau and Kevin Nealon seem to be celebrating Disney's acquisition of Lucasfilm.
