Perrie Edwards' mum has confirmed her daughter is engaged to One Direction star Zayn Malik, after the Little Mix singer was spotted with a diamond ring at the world premiere of One Direction: This Is Us.

Although the couple posed up with their respective Little Mix and 1D bandmates at the London screening on Tuesday, all eyes were on the 20-year-old singer's new accessory.

The X Factor star was wearing a diamond ring on her left hand with Perrie's mum Debbie now confirming that Zayn, also 20, proposed to her daughter over the weekend.

Perrie's excited mother told the Dorset Echo newspaper: 'It's official. I'm over the moon. They are really in love.'

Debbie added that while her daughter is understandably thrilled she didn't want to make an official announcement on Tuesday night, as she was reluctant to overshadow her new fiance's big night.

Perrie's mum revealed in a radio interview how the proposal happened:

'It's wonderful because Zayn is absolutely gorgeous. It's true they got engaged on Sunday and it's absolutely lovely.'

'Perrie loves him to pieces and it's perfect. They get on so well together and understand each other. It's just fabulous.'

A representative for the stars has also confirmed the news to Mail Online: 'Zayn and Perrie are engaged, but any further detail regarding their relationship is private.'

A source has told The Sun: 'Zayn got down on one knee and presented Perrie with the ring. She couldn't believe it. It's a shock to everyone.'

The young couple originally started dating in December 2011 after meeting on set of The X Factor, where Perrie was a finalist with Little Mix.

Although their first attempt at a relationship ended after a few weeks, the couple started dating officially in April 2012.

However, their romance was rocked in January this year when waitress Courtney Webb claimed she spent the night with the pop heart-throb at his London home.

Despite their troubles, Zayn has tried to prove his love for Perrie by getting a cartoon version of her tattooed on his arm.

Dressed in a stunning embellished gown from Brazilian designer Patricia Bonaldi, Perrie stood out as she posed for photos after arriving at the star-studded event with band-mates Leigh-Anne Pinnock and Jade Thirlwall.

But while fourth band-member Jesy Nelson's absence was noted, it was overshadowed by Perrie's eye-catching diamond accessory.

The presence of the curious item sparked inevitable speculation on Twitter, with fans dismissing it as a one-year anniversary ring from Tiffany - bought while the pair were spending some quality time together in Paris in April.

Accessories aside, the Wings singer accompanied her gown with a pair of strappy heels that exposed her black painted toe-nails, while her dyed hair was tied back, drawing attention to the elegantly subtle use of make-up. 

Perrie's two bandmates looked equally stylish – with Leigh-Anne opting for a smart black trouser suit, while Jade went for a classic little black dress and gold sequined blazer jacket from Paul & Joe Sister.

The Geordie star may well have been keen to see the warts-and-all film, but her presence at the event had more to with offering support to boyfriend Zayn on a night that One Direction fans have been anticipating for most of the year. 

Indeed, Perrie was later spotted sharing a kiss with her boyfriend after he posed for a seemingly endless series of shots with hyperventilating fans.

Also attending the premiere with their girlfriends were Zayn's bandmates Liam Payne and Louis Tomlinson.
