Congratulations, Fergie and Josh!

Fergie and Josh Duhamel were married in a Catholic ceremony in front of 200 to 300 people, a wedding guest revealed to Radar.

"They were married as a 14-piece classical orchestra played in the background," the source said. "It was beautiful."

Radar is the first to report that at approximately 5PM Pacific Time (8PM ET), the happy couple said their "I do's" and sealed the deal with a passionate kiss!

The romantic sunset ceremony, which lasted approximately 30 minutes, was celebrated by the cheering guests.

UPDATE 9:00ET: While Fergie and Josh have disco playing inside the ceremony, they're providing a little something for guests standing outside the gates to listen to - the ear-piercing sound of chirping crickets!

The couple's security team has set up four very large speakers outside the party and is playing VERY loud - and annoying - cricket sounds to discourage looky-loos standing on the street.

Stay tuned to Radar throughout the evening for exclusive information on this star-studded event.
