Geri Halliwell's Spice Girl bandmate Mel B "feels really sad" for the 51-year-old amid Christian Horner's controversy at Red Bull.
Horner's private life was thrust into the limelight last month when allegations of 'inappropriate behaviour' were made against him by a female employee at Red Bull.
The F1 team's Austrian parent company, Red Bull GmbH, subsequently launched an investigation into the allegations with Horner eventually being cleared.
The 50-year-old vehemently denied the complaint against him throughout, but the saga has continued to evolve with Max Verstappen's dad calling for the team principal to step down after an anonymous person leaked alleged evidence from the investigation.

Halliwell has shown unity with Horner by appearing by his side at the first two races of the season in Bahrain and Saudi Arabia.
The opening Grand Prix of the year saw Halliwell walk into the paddock hand-in-hand with Horner with the pair sharing a kiss in front of the cameras.
The Spice Girl singer has kept a low profile outside of attending the F1 races, but she was seen for the first time without her husband at the Commonwealth Day Service on Monday.
She still maintains a close relationship with her Spice Girl bandmates with Mel B confirming they've all 'rallied behind her'.
While appearing on Good Morning Britain, Mel B admitted that she and Emma Bunton, Mel C and Victoria Beckham have all been showing their support for Halliwell.
She said: "When you are going through something like that you do need your friends and family and we are all supporting her.
"I feel really sad for Geri."
There was a fresh twist to the Horner saga after the Saudi Arabian Grand Prix when reports emerged in Germany that he was set to be sacked by Red Bull.
It was claimed the major shareholders at Red Bull held a meeting in Dubai on Sunday and were leaning towards dismissing Horner.

However, Red Bull have denied any suggestion Horner is set to be sacked and he still has the backing of the team's bosses.
A spokesperson for Red Bull Racing said: "As Christian has said, he is grateful for the full support of the shareholders and that remains the case."
Horner has grown fed up with the constant speculation and interest following the investigation.

Speaking before the Saudi Arabian Grand Prix, Horner felt it was time to move on from the whole ordeal.
“I think an awful lot has been made out of this,” he said. “Obviously, it has been of great interest in different elements of the media for different reasons. I think the time now is to look forward and draw a line under it.
“We are here to go racing, we are here as a Formula 1 team, and the time now is to focus on what is going on track and the performance of the cars and the drivers, where the spotlight should be during the course of a Grand Prix weekend.
“The scrutiny on my marriage - I've got a beautiful family - it's been very trying. When there [are] children involved, and family involved, it's not pretty. My wife has been phenomenally supportive. The intrusion on my family is enough. It's time to focus on why we are here.”
