The Red Bull team principal insisted that he married the singer because he “loved her”.
The F1 team got off to the perfect start to the season as team drivers Max Verstappen and Sergio Pérez took 1st and 2nd place at the Bahrain Grand Prix.
However his life is just as hectic at home as he doubles up as Red Bulls’ chief executive of Red Bull Racing, Red Bull Powertrains and Red Bull Advanced Technologies at the factory in Milton Keynes.
While his wife, Geri, has just finished writing a book for children titled Rosie Frost and the Falcon Queen.
They got together in 2014 and married in 2015, however, some thought that the relationship would not last, but Horner insists that they “complement each other well”.
He told The Telegraph: “You know, life works in mysterious ways.
“I didn’t marry Geri because she’s a Spice Girl.
“I married her because I fell in love with her.
“It will be 10 years this time next year and we’ve been happily married for seven.
“We’re very different characters but we complement each other well.
“Geri is a force of nature.”
Horner is used to being in the limelight with the success on the track of F1, but was shocked when the Spice Girls announced their reunion tour in 2019.
He added: “Wow, it blew my mind.
“Suddenly you realise the power of that brand.
“They sold out 13 stadiums in five minutes, and that included three nights at Wembley – they could have done another two nights, easy.”
Horner also admitted that he was left embarrassed the first time he tried to kiss Geri.
