The party of all Halloween parties took place in Kate Hudson’s gaff last night.
The Almost Famous actress had the top of the crop of celebs out at her L.A. pad to celebrate the spooky holiday in style.
Not only did Kate manage to get some serious names to her party, but each star made a huge effort for best dressed.
Fancy dress: Kate made a serious effort
Kate styled herself as a sexy Western Gal, posting photos on her Instagram, and of course her snapchat account (@khudsnaps FYI).
“It’s time to party! Before we put the phones away we want to thank @absolutelyx for sponsoring us this year #elyx #skål #LetsDoThis,” Kate captioned tihs pic.
Katy Perry really went all out for her outfit – getting a complete makeover to look like presidential candidate Hilary Clinton.
Using her glam squad to create the perfect Hilary look, Katy donned a short blonde wig and a red pants suit.
“Having a little pre party before I take office #IMWITHME Cheers to @svedkavodka #howtosvedka @hillaryclinton,” she wrote on Instagram.
And just as you thought Katy had out done all the other stars, Jessica Alba and her hubby Cash Warren showed up as Ab Fab (no, seriously).
Amazing: Yes that’s Jessica’s husband in the blonde wig
So if you thought you were making a good effort this year for your fancy dress party – you may want to think again…
