“The Voice” judge Adam Levine was on “The Tonight Show with Jay Leno” on Monday (Oct. 28), where he talked about his recent engagement, his worst date ever, his “bromance” with Blake Shelton and what he’s doing for Halloween this year.

“Famous last words, ‘I’ll never get married.’ I still don’t think you have to get married, unless you meet someone that makes you wanna marry them,” says Levine, coyly, referring to fiancee Behati Prinsloo, a model from Namibia.

As for Halloween, Levine says, “I was a ‘Son’ of Anarchy [last year], I love that show. We’re gonna do ‘Eyes Wide Shut’ [this year], kind of a creepy masquerade thing. It’s gonna be really creepy and awesome.”

He also says that his so-called “bromance” with Shelton is all “bro,” no “mance.” Heh.

“The Voice” airs Monday and Tuesday nights on NBC.
