Say whaaaat?

Yup, Zayn and Perrie are tying the knot according to the Mirror, after Perrie was spotted with a massive sparkler on her ring finger at the premiere of One Direction: This Is Us last night.

The One Direction member and his girlfriend of only 18 months are said to be engaged after insiders close to the couple said Zayn - who met Little Mix singer Perrie backstage at 'The X Factor' in 2011 - went down on one knee at the weekend.

'It was so romantic - Zayn popped the question over the weekend when they were alone together.' says the source to the Mirror. 'It's one of the first weekends they've spent with each other, as they've both been on tours with their bands. He wanted to wait for the perfect moment. All her bandmates were at V Festival, and she couldn't wait to tell them. They're all really excited for her, as the rest of One Direction are for Zayn.'

The couple were inseparable at the premiere last night, with Zayn insisting on being as close to Perrie as possible at all times, just like he did at the Teen Choice Awards last week. And they'd want to be, seeing as Zayn recently had a cartoon of Perrie tattooed on his upper right arm. which Perrie 'loved' apparently (but you kind of have to say that about something so permanent now don't you). 'She loved it, she thinks it's good. It's a good sign.' Zayn said previously.'She was shocked at first but loves it now. She thinks I'm crazy, like everyone else does. To be fair, I am a little bit crazy... I'm happy to be labelled the crazy one of the group.'

Fellow Little Mix member Jesy Nelson prophetically foretold the engagement earlier this year saying: 'Perrie will be the first of us to get engaged, Zayn definitely seems like the kind of person who's gonna ask her to marry him soon. He's an early bloomer.'

'They're just like a married couple anyway. They've got a dog and they literally dress in the same clothes ... I'm getting my hat already.'

As for us? We're getting ready for the inevitable onslaught of date and baby speculation. A Zaby or a Berrbie?
