Perrie was seen with Zayn's mother Trisha and his sisters Safaa and Waliyha Malik for a trip to The Mall shopping centre in Wood Green.
Dressed in a grey blazer and black leggings, Perrie was seen sifting through clothing rails with the family.
While walking between shops, Perrie had her arms crossed, and her diamond engagement ring was firmly in place.
Just last week Zayn announced his decision to leave One Direction after five years.
Zayn, who found fame with the group after they came in third place on The X Factor in 2010, said he wanted to live life like a "normal 22-year-old".
The boys said they respected Zayn's decision, but Niall Horan, Liam Payne, Louis Tomlinson and Harry Styles told fans they would continue as a four-piece.
Just a week before Zayn's departure, he professed his love to fiancée Perrie after pictures emerged of him holding hands with a mystery blonde female.
Zayn broke his silence on Twitter, saying: "I'm 22 years old... I love a girl named Perrie Edwards. And there's a lot of jealous f**ks in this world I'm sorry for what it looks like."
Zayn and Perrie's engagement was confirmed in August 2013. The pair have previously said they've been too busy to plan their nuptials, but it's since been reported that following Zayn's exit they are hoping to get married sooner rather later.
