The 'Little Mix' hitmaker sent gossips into a spin after flashing a diamond ring on her wedding finger at the premiere of the boy band's new tour movie '1D: This Is Us' in London's Leicester Square, reported Daily Mirror.
"It was so romantic - Zayn popped the question over the weekend when they were alone together. 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 the 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," a source said.
The stars, both aged 20 and have been dating from two years, were spotted kissing on the red carpet.
