Adam Levine is officially off the market.
About 275 people, including Robert Downey Jr., Jonah Hill and Jason Segel, attended the ceremony. However, Levine's Voice colleague Blake Shelton is on tour and was thus unable to attend, according to Us.Fleetwood Mac singer Stevie Nicks, who will be a mentor on the upcoming season of The Voice, gave a special performance at the event.
Levine, 35, and Prinsloo, 25, announced their engagement last summer after a year of on-and-off dating. They'll celebrate their honeymoon in South Africa.
