Red Bull Formula 1 team principal Christian Horner will reportedly marry former Spice Girl Geri Halliwell today in a ceremony in South-West London.
The 41-year-old, who has a young daughter with ex-partner Beverley Allan, began dating Halliwell in March last year.
The couple announced their engagement last November and according to reports, the pair will exchange vows at Syon House today.
The Daily Star claims that the former singer will arrive at the venue in one of Horner's racing cars.
It is believed that Halliwell's former bandmates Mel C, Emma Bunton, Mel B and Victoria Beckham, as well as husband David, will attend the wedding.
