Ten of the most epic celebrity Halloween costumes!

Ah, Halloween. The one night out of the year that takes a little more preparation than throwing on some fake tan and putting your hair up.

Halloween costumes take effort, people. Well, usually they do. We won't deny you the opportunity to just put on a witch's hat and be done with it – but with some extra time and dedication just THINK what you could achieve! 

If you're short on inspiration, check out these downright amazing celebrity costumes. Needless to say, we're very jealous. Cue a panic trip to Penney's for last minute supplies!

Here's our top ten countdown…

10. Alexa Chung – The Hamburglar
Childhood memories of birthday parties at McDonald's are suddenly flooding back to us:

9. Neil Patrick Harris and family – Tin Man, Cowardly Lion, Scarecrow and Dorothy
There is no doubt that NPH is the king of family costumes. Sooo adorable. Although little Gideon Scott is clearly having none of this 'posing for a picture' malarkey. Even celebs can't get everything right!

8. Iggy Azalea – Cruella de Vil
Iggy donned this amazing monochrome outfit for Vevo's Halloween party last year in London. And what Cruella costume is complete without a live dalmatian?! Glenn Close would be proud!

7. Cindy Crawford – Slash from Guns N' Roses
You'd never know there was a supermodel under that giant curly wig! Cindy looked every bit the aging rocker for her Halloween costume last year, with husband Rande Gerber accompanying her as Axl Rose. Teamwork at its finest.

6. Fergie and Josh Duhamel – Día de los Muertos skeletons
Fergie paid homage to her great-grandmother's Mexican roots with this very intense Día de los Muertos costume last year. We love the make up!

5. Naya Rivera – Carmen Sandiego
Anyone who sat through a Computers class in primary school will remember sneakily playing Where in the World is Carmen Sandiego? when you were meant to be practising typing with Mavis Beacon. Looks like Naya has the same childhood memory – what a costume!

4. Heidi Klum – every year, ever.
Heidi never fails to impress at her annual Halloween party in New York – our favourite has to be this epic glittery robot from her 2010 bash…

…Although last year's "95-year-old Heidi Klum" costume was pretty cool, too. Bonus points!

3. Neil Patrick Harris and family – Tweedledum, Tweedledee, Alice and the Rabbit
A second mention for NPH and David Burtka – they pull out the stops every year! How cute is little Harper Grace as Alice? Serious outift envy.

2. Ellen DeGeneres – Nicki Minaj
Those fake boobs. Enough said.

1. Melissa McCarthy and Sandra Bullock – two old fishermen
What a genius way for these superstar pals to take Sandra's son Fisher trick-or-treating without attracting attention from fans! We are still laughing at those beards. Win!
