Pixie Lott has obviously decided blondes DON'T have more fun - as she's ditched her famous light curls for an auburn hairdo, instead.
The songstress was spotted working her new 'do at a party to officially launch the NEW Browns Focus at 24 South Molton Street, London.
And she was channelling a distinctly 60s look. There was a monochrome printed long-sleeved A-line minidress, red ankle-strap heels, and thick winged eyeliner.
Her new hair was also of-the-decade with backcombing and a Bardot-esque fringe.
It was only on Friday that we spotted the star looking super-cute in a lemon minidress - that almost matched the colour of her tousled hair.
So what do you think? Do Gentlemen Prefer Blondes, or is this russet look getting a Lott-a love?
We predict she'll be back to blonde in no time.
