Meanwhile, Demi isn't just preparing to be an aunt, they're getting ready to walk down the aisle, too.

The "Confident" singer (who uses she/they pronouns) is engaged to fellow musician Jordan "Jutes" Lutes. He popped the question in December 2023 with a bespoke pear-shape diamond solitaire engagement ring made by N.Y.C. jewelry boutique Material Good, and again in a playful cooking video Demi uploaded in late August.

That same month, Jutes penned a heartfelt tribute to Demi for her 32nd birthday, calling her "my whole world."

You deserve nothing but happiness and love because that’s what you give to everyone you meet," he wrote, before expressing his excitement for their future nuptials. "Ps can’t wait to marry ur fine ass."
