Grey glamour at Cannes film festival as stars show their silver hair

Actors Andie MacDowell, Helen Mirren and Jodie Foster hit the red carpet with silver fox' hair

The red carpet at Cannes film festival has long featured A-list stars in glamorous gowns and with perfect hair. This year, that hair might be grey.

For the premiere of Annette on Tuesday, Andie MacDowell appeared on the red carpet with a mane of greying curls. Helen Mirren also attended, wearing her grey hair up in a chignon, and Jodie Foster, who received an honorary Palme d'Or at the festival, had her hair in a shoulder-length bob with grey streaks visible around her hairline.
