5 Seconds of Summer’s Luke Hemmings has announced he is engaged to his girlfriend, Sierra Deaton.

The singer took to social media to share the exciting news.

In the post, he explained that the engagement took place at least a few weeks ago, but they kept it secret until now.

“With shaking hands but a full heart I proposed to my best friend earlier this year,” he wrote on Instagram.

“I love you Thao and I can’t imagine my life without you,” he added, using her middle name.

Sierra shared the news on her social channels writing: “It was fun keeping this a secret for so long, but my heart is nearly bursting at the seams, can’t wait for forever.”

The couple have been together since 2018.

Sierra is best known for winning the third season of The X Factor in America, as one half of the group Alex & Sierra with her then BF Alex Kinsey.
