Hear that? That’s the sound of thousands of hearts breaking around the world upon hearing the news that 5SOS hottie Luke Hemmings is engaged to girlfriend Sierra Deaton.

Hemmings announced over Instagram on Wednesday that he had proposed to his longtime love earlier this year in an emotional post that featured a bunch of adorable photos of the pair during the special moment.

“With shaking hands but a full heart I proposed to my best friend earlier this year,” he wrote, alongside a series of sweet snaps.

“I love you Thao and I can’t imagine my life without you ❤️ @sierradeaton”

Sierra also shared the exciting news over social media, saying: “It was fun keeping this a secret for so long, but my heart is nearly bursting at the seams.

“Can’t wait for forever.”

According to PEOPLE, Hemmings popped the question in an intimate setting in Malibu, California back in February.

The super cute pair first began dating back in February 2018 and made their relationship Insta-official in August of that year.

For those who haven’t already madly Google-stalked the stunning bride-to-be, Deaton is also a musician herself, competing on the third and final season of X-Factor US as duo Alex & Sierra alongside her ex-boyfriend Alex Kinsey.

Hemmings previously dated Arzaylea Rodriguez from around 2015 until 2017.

Last year, Hemmings revealed that he had written the 5SOS’ track ‘Not In the Same Way’ about his now-fiancee, saying: “Well, it’s about me and my current girlfriend, and she’s incredible.

“Maybe Ashton was there as well, maybe he was writing about someone else, but that’s where I was writing about from,” he told Paper Magazine last year.

“She’s a beautiful human. It could be painted in such a… when the worst moments are written on paper, it doesn’t look very good. It was very important that it was the other side of it, because a lot of the mistakes are mine, you know?”

Aww, congrats guys!
