But - if new paparazzi photos are to be believed - Gigi has bid farewell to her blonde hue in favour of a dark new lewk.
Here's Gigi on November 7th at a London event for her new Maybelline New York collection, where her blonde hair looked *slightly* darker in a top-knot...
And here she is on November 8th with suspiciously dark-looking locks...
There's always a chance that the flashes have made her hair appear darker, so we'll just have to wait for the inevitable "new hair who dis?" Instagram post to know for sure.
Either way, these photos confirm that Gigi can definitely pull off the dark colour.
