UPDATE: It's true! According to Digital Spy, Perrie Edwards' mother called into Real Radio to confirm the engagement. Congrats to the couple!

Back in the spring, Little Mix member Perrie Edwards posted the above photo of herself and her BF, One Direction's Zayn Malik, making pouty lips. She labeled it "My love. My Everything." We know, we melted and went weak in the knees, too.

Well, we're now wondering if the couple has gotten MORE serious, as Edwards was spotted wearing a diamond on her left ring finger at the London premiere (Aug. 20) of 1D's film 'This Is Us.' It looked eerily like an engagement ring. We have to wonder -- are Zayn Malik and Perrie Edwards, both 20, engaged?

Well, have a look at the rock on Edwards' finger for yourself.

It's understated and gorgeous.

We'll pause to gush over the starburst effect on the bodice of her black dress, because that's also stunning. And we love her slicked back hair, too. You can see how pretty she looked below.

But that ring!

If there was ever a time to debut such a sparkler, it's when all the world --okay, Directioners and the pop music media-- is watching at an event like this.

So far, no word if this indeed an engagement ring. It'd be quite the time for Zayn and Perrie to offer a telltale sign that they've deepened their commitment.

Or maybe it was just a pretty accessory...
