Horner, who is married to Spice Girl Geri Horner, is a divisive figure among F1 fans due to his controversial way of handling team issues both internally and with rivals.
Last year, Horner was involved in a stunning power struggle at Red Bull after he was embroiled in a sexting scandal in which an employee accused him of making suggestive remarks.
CHRISTIAN HORNER was brutally booed at the F1 75 launch event at the O2 Arena.
Clips of the crowd reaction were shared on social media, with one fan remarking: "Oh my god the booing for Christian Horner was even worse than they showed on TV.".
But when Red Bull boss Horner took to the stage he was greeted by a chorus of boos.
