Hear that? It's the sound of a million hearts breaking.

One Direction's Zayn Malik is engaged to Little Mix singer Perrie Edwards, the bride-to-be's brother confirmed via Twitter.

"Right. My sister and Zayn ARE Engaged! It's true!" Jonnie Edwards tweeted. "You seen the ring on the finger and all that Jazz! CONGRATS!!!"

Malik and Edwards, 20, hit the red carpet Tuesday night for the London premiere of the boy band's documentary, "One Direction: This Is Us," with Edwards flaunting the new engagement ring on her left hand.

"Aww the trends," Perrie Edwards noted this morning. "#Zerrie #CongratsZaynandPerrie

Malik proposed last weekend after two years of dating, according to British newspaper 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," a source told the newspaper. "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."
