Halsey posted the sweetest message to her boyfriend Yungblud on his birthday.

The "Without Me" singer took to social media on Monday (August 5) to give her man some love on his 22nd birthday.

"darling dom. everyone who has met you in this life, for any amount of time at all, will be changed forever because of it," she wrote on Instagram. "for some, in small ways they won’t even realize. for others, in a life-changing wave. and every single one of them will be better, from having crossed your path for even a second. you leave an irrevocable shine on every soul you come in contact with. mine is gleaming. happy birthday, I love you."

"I love you," Yungblud replied in the comments section.

She also shared an adorable montage on Twitter, giving fans a glimpse into their nearly one-year-long relationship through personal, never-before-seen videos and photos of them. There's a clip from the British singer's birthday party, as well as a ton more PDA-filled content as the Oasis song "She's Electric" plays in the background.

"happy birthday squish," Halsey affectionately wrote.

The couple first sparked dating rumors in November 2018 after they were spotted leaving a recording studio together. However, Halsey later confirmed the romance when she posted their first Instagram photo in January 2019.
