After a year-long engagement, Adam Levine and Victoria’s Secret model Behati Prinsloo finally tied the knot over the weekend in a wedding that was filled with some of the biggest names in Hollywood. Robert Downey Jr., Jason Segel, and Prinsloo’s fellow supermodel Coco Rocha were in attendance at the ceremony, which was officiated by 22 Jump Street star Jonah Hill.

The Maroon 5 frontman asked his longtime friend Hill to preside over the ceremony in Los Cabos, Mexico, in hopes of turning his nuptials into a fun-filled event.

“Adam knew that he was putting himself good hands by having Jonah officiate,” an insider told Us Weekly. “He and Behati set out to make this the most fun wedding that anybody had ever experienced and they truly did just that.”

“Jonah was hysterical. He was telling so many jokes, but then in the middle would be so sweet and sincere,” a source told E! News.

Hill explained on the Howard Stern show in June that he and Levine have been close friends since childhood.

“Our dads met in the principal’s office in junior high. We were in carpool, we lived at each other’s houses.”

The ceremony was held at the Flora Farms in Los Cabos, and around 300 guests were in attendance. Despite having several Victoria’s Secret model friends as her bridesmaids, Prinsloo kept all eyes on her in her stunning blush-colored, hand-embroidered, custom Marchesa gown and veil. The wedding included musical performances by Maroon 5’s James Valentine and Stevie Nicks.
