Ah celebrities. They're just like us really. 

Even they like to let their hair down and dress up for Halloween. Of course the difference is they can afford to hire designers and make up artists to perfect their costumes. 

From P Diddy to Kyle MacLachlan, Kim Kardashian to Bette Middler, we've compiled a gallery of our favourite celebrity costumes from down through the years. 

Special shoutout to Heidi Klum. When she does Halloween she really goes for it!
