The Little Mix star posted an Instagram story as she opened a Net-A-Porter advent calendar gifted to her by Oxlade-Chamberlain’s mum Wendy.
Edwards posted a red heart alongside the caption: “Why is my mother-in-law the best/cutest person ever? I actually LOVE her.”
Despite not being engaged, fans were quick to question whether Edwards, who has been with the Liverpool midfielder since 2016, had secretly walked down the aisle.
One wrote: “Did Perrie and Alex get married did I miss anything?”
Another commented: “Did Perrie and Alex get married im shaking you guys.”
A third tweeted: “I love seeing how happy Perrie is with Alex. They are probably gonna get married.”

Standard Online has contacted representatives for Edwards and Oxlade-Chamberlain for comment.
Earlier this week, Edwards broke her silence on the recent spat between Little Mix and Piers Morgan.
The Good Morning Britain host hit out at the X Factor winners earlier this month, accusing them of “using sex to sell records” after they released a naked promo shot for new single Strip.
Edwards, 25, told Capital FM: “I love watching Piers Morgan because he makes people cry and gets the dirt from them.”
Morgan later fired back at her comments, claiming the foursome are not “big enough” to feature on his ITV series Life Stories, which sees him delve into the lives of famous faces.
He said: “So they pretend to hate me, but they love me. She’s talking about Life Stories I think. They won’t be on there because they’re not big enough I’m afraid.”
