Five-year-old Grant pegged both when he proposed to pop star Demi Lovato during a stop on her Demi World Tour in Moline, Illinois, over the weekend.

Lovato is making no secret of new relationship, posting it to her Instagram account.

"Oh and by the way guys...... I'M ENGAGED!!!!!!!!!!!!!!!!!" she said. "❤️❤️❤️ thank you to my future husband Grant... #CUTESTEVER #demiworldtour."

Grant got the ball rolling with a sign. "Demi I have a ring for you," it said.

That got him on stage, but Demi, 22, expected a proper proposal -- the down-on-one-knee type.

"Demi, will you marry me?" he asked.

"I will," Lovato squealed.

Then Grant put a ring on it, and the newly "engaged" couple sealed the deal with hug and a kiss -- on the cheek.

We're still waiting to hear from Lovato's 34-year-old boyfriend, Wilmer Valderrama, to find out how he feels about being tossed aside for a (much) younger man.
