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.
