Adam Levine is clearly head over heels for his fiancee Behati Prinsloo.

"She's the greatest ever," The Voice coach said during a Thursday appearance on The Ellen DeGeneres Show, according to Us Weekly.

Levine, 34, reportedly told Ellen DeGeneres he and his wife-to-be, 24, have one funny trait in common.

"We're both super messy. It looks like a tornado hit wherever we hang out," Levine joked.

"There's a big difference between dirty and messy. Dirty's gross, it means you're unhygienic, you don't shower. Messy's like, I don't care that that shirt's on the floor."

Levine was named People magazine's "Sexiest Man Alive" for the year 2013.

Levine began dating Prinsloo, a Victoria's Secret model, last year. After a brief split in late spring, the couple reconciled and got engaged in July. The Maroon 5 rocker has served as a coach on The Voice since its inception five seasons ago.
