The Maroon 5 frontman announced his engagement to Victoria's Secret model Behati in July, and was asked about his surprise engagement on The Tonight Show with Jay Leno.
Adam told Jay Leno: "Famous last words, 'I'll never get married'.
"I still don't necessarily think you have to get married unless you meet someone that makes you want to marry them. And then you marry them and it's wonderful."
Adam proposed to Behati in Los Angeles, and the engagement was happy news for the couple who had recently reunited after splitting in March.
The couple, who began dating October last year when they made their debut at GQ's Gentleman Ball in New York, are now happier than ever, but they haven't set a date for their big day yet!
"We're working on it," Adam continued.
