5 Seconds of Summer's Luke Hemmings got engaged to his girlfriend Sierra Deaton after a sweet proposal.
The star and his now-fiancé met in 2017 and dated for around four years before he got down on one knee.
He shared an amazing series of photos on Instagram with his 6.8 million followers.
"With shaking hands but a full heart I proposed to my best friend earlier this year," the 24-year-old guitarist wrote.
"I love you Thao and I can’t imagine my life without you @sierradeaton."
The first snap showed Sierra holding onto Luke's face as she leaned in for a kiss. The gorgeous ring can be seen in the photo.
In another snap, Luke and Sierra are beaming with joy as he slipped the ring onto her finger.
One stunning photo showed Sierra and Luke kissing in front of a picturesque mountainous backdrop.
Sierra, who is also a musician, shared the same series of photos and wrote: "It was fun keeping this a secret for so long, but my heart is nearly bursting at the seams. can’t wait for forever."
Singer Max Schneider took to the comment section to write: "Congrats my brother" while One Republic's Ryan Tedder commented with two heart emojis.
Sierra competed in the third season of X Factor US when she was in the dup Alex & Sierra with her ex-boyfriend Alex Kinsey.
She went on to release songs under the stage name Essy and has provided vocals for 5SOS.
Luke had said 5SOS's track Not In the Same Way was about his fiancé.
"Well, it's about me and my current girlfriend. She's incredible," he said in an interview.
"Maybe Ashton was there as well, maybe he was writing about someone else, but that's where I was writing about from.
"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?"
