Hill 'officiated Levine wedding'

Jonah Hill reportedly officiated Adam Levine and Behati Prinsloo’s wedding.

The Maroon 5 frontman and Victoria’s Secret model reportedly exchanged vows Saturday evening in Los Cabos, Mexico with several celebrity guests present.

But E! News reports Jonah may have been more involved in the ceremony than originally thought. A source tells the outlet the actor had friends and family of the couple cracking up as he pronounced them man and wife.

"Jonah was hysterical. He was telling so many jokes, but then in the middle would be so sweet and sincere,” the insider said.

The 22 Jump Street star has known Adam for a “long time”, and is said to have made mention of the rocker’s “wonderful” qualities, as well as how “perfect” the bride and groom are for each other.

Behati’s father, who E! reports is a minister, is also said to have given a blessing during the ceremony.

The event was described as “loose, romantic and fun”, with Adam and Behati reading vows they had written themselves.

Jason Segel, Erin Heatherton, Candice Swanepoel, Adam’s Maroon 5 bandmates James Valentine and Jesse Carmichael, as well as Robert Downey Jr. and model Coco Rocha, were also reportedly among guests who watched as the couple entertained them with tunes later in the evening.

Adam reportedly joined Stevie Nicks on stage, and later coaxed his new bride into singing Bright Eyes, a song she apparently told him she wanted to perform at her wedding when they first began dating.

“It was kind of a bet between them. He introduced her and she sang it. She had a beautiful voice,” a source said.

Adam and Behati began dating in 2012 and announced their engagement in July of last year.

The couple are reportedly honeymooning in South Africa.
