Robbie Williams married his girlfriend Ayda Field in the grounds of his Beverly Hills mansion, his spokesman has confirmed.
The pair exchanged vows in front of family and friends during a ceremony at the property on Saturday.
Spokesman Murray Chalmers said: "Robbie Williams and Ayda Field were married yesterday, August 7, in a ceremony held in the grounds of the home they share in Los Angeles."
The couple did their utmost to keep the ceremony secret and kept the world's media at bay after agreeing a deal with Hello! magazine for the wedding photos.
The singer, 36, is said to have donned a black tuxedo while his bride, 31, wore a white dress with her hair pinned up.
Celebrity website People.com said 75 guests attended the 30-minute ceremony.
Several marquees were pictured in the grounds of Williams' LA mansion as details of the event were leaked.
Williams' father Pete Conway told the News of the World: "At last, Rob is happy. That's what you want for your kids and this is the happiest I've seen him. Ayda is so beautiful and delightful and so lovely and just so right for him. They are brilliant together."
The Stoke-born star's Take That bandmates - whom he dramatically rejoined last month - are not thought to have flown over for the ceremony. Instead they reportedly sent a series of messages to be read out.
Pictures of the wedding will be revealed in Wednesday's edition of Hello!, the magazine added.
