Perrie flaunted her dazzling diamond ring in a series of snaps posted to Twitter yesterday (21 August), after her mum confirmed her engagement to Zayn this week.
Perrie showed off her new rock and pulled funny faces as she posed with her best friend Katherine.
Accompanying the photo, Katherine said: "So it's official, Perrie & Zayn are engaged! Couldn't be happier! Love You Both! :') #CongratsPerrieAndZayn."
Perrie and Zayn sparked engagement rumours when she was spotted with the large diamond band on her finger at One Direction's movie premeire, This Is Us, in London on Tuesday night (20 August).
After much speculation it was soon confirmed by Perrie's mum Debbie, who revealed to Real Radio on Wednesday (21 August) that Zayn proposed to her daughter at the weekend and asked for her permission before getting down on one knee.
Zayn, who has got a cartoon-style image of Perrie tattooed on his arm, has also spoken briefly on the subject since it was confirmed, adding: "We're really happy."
Zayn and Perrie began dating each other in April 2012, soon after Little Mix won The X Factor.
