Geri Halliwell remains 'totally invested' in her marriage to Christian Horner despite the 51-year-old's sudden departure from Red Bull earlier this week.
Horner was relieved of his duties by the Formula One side after two decades in the job.
In a surprising move, Red Bull also confirmed that former Racing Bulls chief Laurent Makies would be taking charge.
The decision comes nearly 18 months after a female Red Bull employee accused Horner of 'inappropriate behaviour'. Hundreds of WhatsApp messages allegedly exchanged between the pair were leaked to the press, leading to uncertainty over the Briton's position.

It is claimed, however, that the Spice Girls icon remains 'totally invested' in their marriage at the current moment in time.
"Geri has already begun distancing herself by going by Halliwell-Horner when writing her books," an insider is quoted as saying.
