The 22 Jump Street star officiated the nuptials of the Maroon 5 frontman to Behati Prinsloo on Saturday in Cabo San Lucas, Mexico. Jonah, whose brother Jordan Feldstein is Adam’s manager, brought on the laughs and turned on his charm for the special day.
“Jonah was hysterical,” a source told E! News. “He was telling so many jokes, but then in the middle would be so sweet and sincere.”
The “Maps” singer and Oscar-nominated actor have been friends for years. During the ceremony, Jonah gushed about his longtime friend, calling him a “wonderful guy.”
“Our dads met in the principal’s office in junior high,” Jonah told Howard Stern about his relationship with Adam earlier this summer. “We were in carpool, we lived at each other’s houses.”
Jonah wasn’t the only famous face in attendance. Robert Downey Jr., Coco Rocha, and Jason Segel witnessed the judge on The Voice say “I do.” Stevie Nicks was also in attendance and performed for the newlyweds.
“Adam knew that he was putting himself in good hands by having Jonah officiate,” a source 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.”
