British media say pop singer Robbie Williams is to marry his girlfriend, US actress Ayda Field, in an intimate ceremony.
The Daily Mail tabloid says the 36-year-old pop star plans to have a low-key wedding among close friends and family in California on Saturday.
There are conflicting reports about the location of the ceremony.
The Daily Mail said the wedding would be held in Williams' mansion in Beverly Hills, while other reports say the singer will tie the knot with Field on the island of Santa Catalina off the coast of California.
His represenatives declined to comment on media reports of his wedding.
Williams is popular in Britain and the rest of Europe, first as a member of the boy band Take That, and later when he pursued a solo singing career.
