Zayn Malik's Ex Perrie Edwards -- Diamond Ring Trolls One Direction & Little Mix Fans

EXCLUSIVE

Zayn Malik's ex-fiancee Perrie Edwards looks like a desperate chick who's still longing for the guy who dumped her in a new Little Mix music video -- but we've learned it's not what it seems.

The vid for "Love Me Like You" dropped Friday, and fans instantly noticed the engagement diamond on Perrie's finger. People were wondering why she was still wearing it, since they broke up 2 months ago. Was it a dig at Zayn or wishful thinking?

It's neither. We found out the video was filmed around 6 months ago, when Perrie and Zayn were still a thing. Sources who were on the set tell us she kept the ring on during shooting because they were very much in love.

But y'know ... things change. The former One Direction singer broke things off in August, and Perrie didn't take it well.

Silver lining: Perrie gets some pub for her new song.
