Christian Horner has addressed rumours that he and his wife Geri Halliwell plan to star in a documentary.

Reports on Friday suggested the couple had been approached to make a “really personal” fly-on-the-wall TV series following recent “speculation about their relationship”.

The Red Bull boss has faced intense scrutiny in recent weeks following allegations made against him by a female colleague. Horner has always denied the claims.

He told the PA news agency: “There is a lot being written about different things, but there are absolutely no plans to do a family documentary.

“Netflix do enough, and you see enough of the behind-the-scenes on that. So where that report has come from, I have absolutely no idea.”

During the Bahrain Grand Prix last month, Geri, who found fame in 1990s girl group the Spice Girls, appeared alongside her embattled husband to show her support, with the couple sharing a kiss.

Red Bull Racing’s parent company, Red Bull GmbH, announced on February 5 that Horner was being investigated following an accusation of “inappropriate behaviour”.

Horner emphatically denied the claim and the 50-year-old stayed on as team principal after Red Bull confirmed the grievance had been dismissed on February 28.

Twenty-four hours later, messages and several images apparently exchanged between Horner and the complainant were leaked.

The complainant has since appealed against the decision to clear Horner of controlling behaviour, it is understood.
