Taking to Instagram last night (7 June), Perrie decided to unveil Zayn's rather unusual hair dye choice by sharing a loved-up photo of the pair.
And while the couple do look pretty cute in the snap, we just can't stop staring at Zayn's new hue!
In her photo, Perrie can be seen looking pretty smitten as she nestles into the chest of her hubbie-to-be. Zayn, meanwhile, is pictured posing for the camera without seeming too phased about debuting his green locks for the first time.
While we're not sure we could handle our beaus taking hair inspo from Batman's Joker, Perrie didn't seem to mind.
Captioning her photo, she said: "#GreenHairDontCare."
And it seems fans of the former One Direction star didn't seem to mind too much either, with over 300,000 liking the photo.
Some, as expected, weren't so keen and seemed a little shocked at Zayn's new 'do. Well it's definitely not your average trip to the salon, is it?
Perrie's post of herself and Zayn came after she and her Little Mix bandmates took to the stage at Capital FM's Summertime Ball.
The girls performed their new single 'Black Magic' for the first time to the 80,000 strong crowd, telling the radio station backstage they loved every minute of doing so.
The track has been lifted from Little Mix's third album and Perrie, Jesy Nelson, Jade Thirlwall and Leigh-Anne Pinnock have said they are so excited for fans to hear their new music after taking a new direction.
"It's scary because we've never done this style before," they said. "But we're excited because it's a new lane, a new year and we're feeling very positive. We just want it to be perfect."
One Direction also performed at Wembley Stadium on Saturday, taking to the stage as a four piece after Zayn's exit.
Earlier this year, Zayn quit One Direction following five years of being in the boyband. He claimed he wanted the chance to be a "normal 22-year-old" again away from the spotlight.
