Perrie is currently Down Under with her bandmates doing promotional work and performances to promote their latest single 'Move' and new album Salute.
The girls, who landed in Sydney, Australia last Friday (18 October), visited radio station 2Day FM, but Perrie got a sudden surprise when she saw the cutout of Zayn staring straight at her!
Perrie, 20, is seen holding her hands up to Zayn's nose, meanwhile bandmate Leigh-Anne Pinnock is seen cosying up to the cardboard cutout of 1D's Liam Payne, pretending to cover his mouth.
Posting a photo on Little Mix's official Instagram page, they said: "Look who we bumped into..."
Singers Perrie and Zayn, who got engaged on 18 August, may be busy touring the world, but they still had time for a brief reunion this week.
Zayn, who was already in Australia on tour with 1D, was spotted flying out of Sydney on Sunday (19 October) before jetting back to Brisbane for the boy band's sold out show.
Little Mix, who rose to fame as the winners of The X Factor UK in 2011 performed their new single 'Move' on the Australian version of the talent show last night.
