The couple - who got engaged this summer - have become proud parents to an adorable cat called Prada, introducing their new feline friend via the official Little Mix Twitter page.
They captioned the snap: ''Say hello to the new member of the family, Prada :) Perrie&Zayn
The besotted stars, both aged 20, then uploaded a Vine video of Perrie cooing over the long-haired kitty.
They wrote: ''DespicableMeMoment She's so fluffy I'm gunna die! :D
Perrie was no doubt responsible for naming the kitten Prada, since the Little Mix singer has the most high-end fashion tastes out of all her bandmates and boasts wardrobe full of designer labels.
She recently said: ''I adore my Prada handbag. And I love my Louis Vuitton shoes.''
The 'Move' singer has already invited her fellow Little Mixers Jesy Nelson, Leigh-Anne Pinnock and Jade Thirlwall to be her bridesmaids, even though she and the One Direction hunk have yet to set a date for the wedding.
She revealed: ''It's going to be a massive circus. I actually wanted to have quite a small wedding, but then all the girls in my family are desperate to come and would like to be bridesmaids too.
''I realise my wedding is every journalist's dream. It's going to be like the movie '27 Dresses' where the bride has like a billion bridesmaids.''
