The Maroon 5 frontman and the Victoria's Secret Angel tied the knot in a romantic outdoor ceremony in Los Cabos, Mexico on Saturday night.
The couple gathered their 275 guests at Flora Farm – a ten-acre venue which features a hilltop altar according to the official website.
"She was watching the show on a monitor with others backstage," an audience member told the publication.
"Her hair was up in a bun and she wore a low-cut, white sleeveless top and dark jeans." The Sports Illustrated model recently made headlines when she attended the prom of Jake Davidson after supermodel Kate Upton cancelled on the high school senior.
Meanwhile, Maroon 5 were forced to postpone their 2013 summer tour and rescheduled the dates for early 2014.
