Pixie Lott attended the Julien Macdonald show wearing her signature peroxide blonde locks in a high bun.
But just a few hours later, the popstar stepped out sporting a completely different look entirely, having dyed her hair brunette.
The star took to Twitter to share a picture of her drastic new look. "Hair swap spur of the moment decision," she wrote.
Earlier in the day, Pixie wore a fire engine red cutaway dress to cheer on Julien as he presented his new dazzling collection.
She later paired her new look with a 70s style, high-necked geometric monochrome print dress to party the night away.
Pixie had a front row seat alongside Eliza Doolittle and Paloma Faith at Julien Macdonald.
Paloma, who went backstage to congratulate Julien on an "amazing" show, dazzled in a one-shoulder white gown with shoulder embellishments. She paired the dramatic, floor-sweeping number with a white hat.
