X Factor judge Cheryl showed off a lighter hairdo as she arrived in the south of France yesterday with husband Jean-Bernard Fernandez-Versini.
The former Girls Aloud singer was spotted strolling through Nice airport wearing a preppy yellow mini dress and thigh-high leather boots.
Cheryl will be walking the red carpet today in her role as an ambassador of hair brand L'Oreal.
L'Oréal Paris UK shared a photo of Cheryl in a dressing gown yesterday, captioning the snap: "Relaxing with @CherylOfficial before the #Cannes2015 red carpet tomorrow #InsideCannes."
This morning, she teased her appearance in a new Instagram video. Wearing a blue lace outfit and embracing her newly-dyed shade of locks, Cheryl pulled off her best pout while winking at the camera.
She captioned the video: "Morning Cannes lorealparisuk #Cannes2015."
No doubt Cannes Film Festival holds lots of memories for Cheryl, as it was just after the annual extravaganza last year that she was linked to Jean-Bernard. The pair married a few months later in a secret ceremony on the Caribbean island of Mustique.
