So THAT'S where she gets those eyebrows! Cara Delevingne Instagrams pictures of her 101-year-old grandmother - and yes, she was a model too

She shot to fame as the bushy-browed model with a versatile look that made every designer want her to front their campaign.

And judging by these never-before-seen snaps of Cara Delevingne's grandmother, her good looks didn't come out of nowhere.
The 20-year-old supermodel took to Instagram to share vintage and present day photographs of her mother's mother, saying 'Happy 101st birthday to the most inspirational woman in the world!! My granny Gaga #lookatthosebrows.'

So THAT's where the eyebrows came from! Cara Delevingne uploaded this vintage snap of her grandmother to Instagram; the pair look almost identical

Just one glance at the snaps show that Cara is the spitting image of her grandmother, and reveals exactly where those iconic brows came from.

Cara's grandmother, Janine Sheffield, was married to British pirate radio station Radio Caroline founder Sir Jocelyn Stevens.

Like Cara, she was a former model.

She was also a lady-in-waiting to Princess Margaret, and she and Sir Jocelyn were a key part of Margaret’s coveted Mustique set.

After the marriage ended in 1979, Sir Jocelyn Stevens embarked on a long romance with philanthropist Dame Vivien Duffield, whose father left her a £45 million fortune.

In 2005 they split, and Sir Jocelyn — nicknamed ‘the Piranha’ for his ferocious temper — went on to marry society beauty Emma Cheape, then 54 and 22 years his junior.

While we are more accustomed to seeing her stomp down the runway or partying with Rihanna, these candid Instagram photos give Cara's two million followers a rare insight into her family life.

Just last week she was partying into the early hours at Glastonbury with the likes of Suki Waterhouse, Alexa Chung and Rita Ora.

But clearly the youngster doesn't need any rest: she has been hard at work as the face of yet another high-fashion campaign.

The 20-year-old model has just been unveiled as the face of Fendi's Autumn/Winter 13 campaign, adding to a burgeoning list that already includes Mulberry, Saint Laurent and YSL beauty.

The campaign, named Roman Skyline, was shot by Cara's close friend and Chanel creative director, Karl Lagerfeld.
