The 42-year-old singer and his wife, Ayda Field, tried to get the case dismissed by counter-suing, but a judge has insisted they must attend court in Los Angeles in August to face Gilles De Bonfilhs' claims.

Gilles was paid £35 an hour to run errands for the celebrity couple, but was sacked from the job after 60 days amid claims of ­misconduct and negligence.

Since then, he has alleged he was sexually harassed by Ayda, who he claims disclosed "­information about the nature and frequency of her sexual activity and exposing her naked body".

As part of his claim, Gilles is requesting £17,000 and an apology.

The judge has encouraged both parties to reach a settlement out of court. But if that is not achieved, they will come face-to-face in court.

Meanwhile, the couple released a statement last year in which they strongly denied the accusations, saying they have no "substance".

It read: "The claims being made by a disgruntled former employee, after he was sacked for serious misconduct, are entirely without substance."
