When Adam Levine and model Behati Prinsloo tied the knot on July 19 in San José del Cabo, Mexico, he called upon one of his closest pals to officiate: 22 Jump Street star Jonah Hill.
The actor, 30, did not disappoint.
Hill was "funny, charming and very sentimental," a guest tells PEOPLE in this week's issue.
Levine and Hill share a longtime friendship: They have been friends since childhood – along with fellow pal and groomsman Jason Segel – and Hill's older brother, Jordan Feldstein, manages the Maroon 5 frontman.
"Jonah is my little bro," the Grammy winner, 35, recently told PEOPLE. "That's my boy."
