Just as we were starting to get used to there being TWO Waterhouses in the modelling world, another has burst on to the scene! Suki and Immy's younger sister Maddi has kicked off her career in the industry with a cover for the teen edition of Tatler magazine.
The 16-year-old looks fresh-faced in the shot, bearing more than a passing resemblance to her model sisters.

In an accompanying interview, Suki, 23, quizzed her little sister on their relationship, shopping and self-love.
Maddi, who has over 34,000 followers on Instagram, revealed that Suki and Immy picked out her outfit for her first day at school – a "white collared shirt, black jeans and black trainers".
Suki also asked her if she does anything to help herself "in a world where we're all made to feel ugly?". Maddi's reply hinted at wisdom beyond her years.
"Well, I have affirmations on my mirror that say things like, 'I am beautiful inside and out', and 'I am strong and confident'," she said.
"You say them to yourself everyday so that you start to believe them."

Suki and Immy have been making their mark as the latest sister duo in the modelling world, making several front row appearances together in matching ensembles.
They also appeared in their first campaign together for MyTheresa.com and Tommy Hilfiger.
