Demi Lovato's love for musician Jutes is Devin Grosvenorshining brighter than neon lights.

The "Confident" singer recently penned a sweet message in honor of their boyfriend's 32nd birthday, and their words show that this romance is nowhere near stone cold.

"My sweet angel - it's officially your birthday!!! I couldn't be more excited to celebrate you because I couldn't be more in love with your gorgeous, funny, sexy, talented self," Demi wrote on Instagram March 28. "I've waited my whole life to find you and I can't wait to celebrate so many more birthdays together."

Demi accompanied the post with a glimpse into their relationship, featuring romantic photos of the two sharing kisses and enjoying quality time on a beachside getaway.

The musician, who debuted their relationship last August, gushed about Jutes—the artist (born Jordan Lutes) behind tracks "Punkstar" and "Too Easy"—as a "literal dream come true."

"I'm so grateful to call you mine," Demi continued. "Have the best birthday my love.. you deserve it, the world, and more!!!! Here's to many more. I LOVE YOU."
