Ariana Grande's ponytail is the new face of Givenchy

Ariana Grande, and her trademark high ponytail, are the new face of Givenchy, the house behind Meghan Markle's wedding dress.

The announcement was teased over several days on Instagram, but fans guessed at the singer's identity thanks to her hairstyle.

In the series of black and white shots, you can see Ariana wearing a black cocktail dress, an homage to Audrey Hepburn, who of course wore that iconic Givenchy LBD in Breakfast at Tiffany's.

When she was finally revealed, you didn't see her face, just a simple swish of her ponytail, another nod to the Truman Capote film, which opens with Audrey staring at the famous jewellers' window display, from the back.

In a statement, the brand said, 'It is with great excitement that the House of Givenchy reveals its new face — a strong, independent woman of refreshing character and style: the multi-talented Ariana Grande.

'A modern muse and the voice of a generation, Ariana has emerged as one of the most influential forces in pop culture today. A Grammy award-winning performer, songwriter and singer, she naturally embodies the spirit of the Givenchy woman with impertinence, generosity and a lightning wit — all cloaked in a touch of mystery,' the statement continued.
