While the rest of the US is (un)dressing as Kelly Osbourne shared this snap of herself done up as Christina Hendricks from Mad Men on her Instagram feed, having dressed up early to film her TV show Fashion Police's Halloween special.

And she even went to the length of getting an exact copy made by the same dressmaker who supplied Christina's Emmys gown.

She wrote: "What do you guys think? @csiriano made me the exact same dress he made the #stunning #ChristinaHendricks for the #emmys so I could dress up as her for our @E_FashionPolice #halloween episode! I hope I did here justice!! ps I had to wear 3 bras!!"

We wonder if she borrowed the red wig from her mum Sharon Osbourne?

Kels recently praised her pal Taylor Swift's baking skills .
