Robbie Williams is set to marry his girlfriend Ayda Field on Saturday (August 7), it's been reported.

The ceremony will take place on the romantic island of Santa Catalina off the coast of Los Angeles.

Williams met Field, an actress and comedienne, in 2006.

The Sun reports that wedding guests are expected to include Williams's family and best friend Jonathan Wilkes.

But the other members of Take That – Gary Barlow, Jason Orange, Howard Donald and Mark Owen – are not expected to attend.

Williams rejoined the boyband last month for a new album and tour, which is expected to take place next year.
