Aside from Two Pints Of Lager And A Packet Of Crisps, Sheridan Smith is arguably most famous for taking on the title role in Legally Blonde.
But it's now more of a case of Legally Brunette for the 31-year-old actress, who debuted her newly-dyed hair on a night out in London on Saturday.
Sheridan's new locks are several shades darker than her formerly bright blonde hair, taking her to a light brown colour.

Explaining her new look on Twitter, Sheridan told her fans that she had had to colour her hair for a new role, which will see her film in Ireland.
As well as her darker hair, Sheridan showed off a flash of stomach in a cropped black top and low-slung trousers as she joined pals including Coronation Street's Antony Cotton on the evening out.
Sheridan teamed her outfit with an orange cardigan tied over the top, and finished off the ensemble with black court shoes.

And despite her new look, Sheridan was still recognised by fans on the evening out, and was grabbed by one particularly eager birthday girl and her friends for a quick photo opportunity.
But it seems Sheridan may have over-indulged slightly on the alcohol front on the evening out, as she informed her followers on Sunday morning that she had made an embarrassing error while catching a flight to Dublin.
She wrote: 'Shouldn't admit this,just queued 4 ages to get thru security once thru took a wrong turn ended up at baggage reclaim.
Whoops! Sheridan and her friends couldn't resist laughing at a paparazzo who fell over while trying to take their picture
'Only I could do something so stupid.'
And when one fan suggested she could blame her mistake on being blonde, Sheridan replied: 'I can't even use the Blonde excuse cause they've dyed my hair dark for this role! I'm just a dumb ass :)'
