The Sexiest Man Alive is now the Sexiest Married Man Alive. 

Adam Levine wed Victoria's Secret model Behati Prinsloo Friday night in Los Cabos, Mexico -- and Jonah Hill officiated the union! A source tells E! News, "Jonah was hysterical. He was telling so many jokes, but then in the middle would be so sweet and sincere."

Among the guests were Robert Downey Junior and Stevie Nicks, who sang with the Maroon 5 frontman during the reception.

The Voice mentor and the Namibian [pr: nuh-MIH-bee-uhn] beauty began dating in 2012, shortly after Adam broke up with another Victoria's Secret model, Anne Vyalitsynalast. Adam also dated Sports Illustrated swimsuit model Nina Agdal while he was on a break from Behati in 2013.
