Make me look like this! Stars - and the inspirations behind their hairdos

If you got a sense of deja vu when  cut her 'Hermione hair', or think Lily Allen's bob reminds you of someone, you wouldn't be far off the mark.
In fact, when the Harry Potter actress decided to go for the chop, she had a specific look in mind.
'When I went in to my hairdresser, I took a picture of Mia Farrow and said: "I want to look like this,"' she said in an interview last month.

And as it suited Farrow, it suits her. The two women share a similar face shape with high cheekbones - highly neccessary for this most unforgiving hairstyle.
But Emma is not the only one to take her style lead from a star from a different era.
Sienna Miller's tousled blonde locks are not unlike Goldie Hawn's, while Lily Allen's flapper-style bob takes inspiration from silent movie actress Louise Brooks.

Blonde bombshell: Sienna Miller's tumbling locks are not unlike Goldie Hawn's

Of course it's easy to see why Lily, Sienna and co have followed these style leads - they ooze old school glamour.
It's less easy to understand why Kelly Osbourne followed in the footsteps of the late Queen Mother however.

Lock up your dalmatians: George Lamb's 'do reminds us of Cruella de Vil

While short lavender-hued curls are fitting for women of a certain age, it was a surprise to see young Kelly go for such an ageing look.
More bizarre still is silver fox television presenter George Lamb's uncanny resemblance to Cruella de Vil - the infamous heroine of 101 Dalmatians.
Fame may bring money, but clearly, it can't buy you style.
