The supermodel, who was in town supporting F1’s all-female feeder series F1 Academy, jumped in the passenger seat of the $136,000 Mercedes-Benz AMG GT with Hamilton on Saturday.
‘Oh my god,’ she shrieked, adding, ‘holy h**t’, I’m gonna cry.’
At one point she jokingly told the Mercedes driver, ‘I literally hate you,’ while he sped around a corner ahead of Sunday’s Miami Grand Prix.
Jenner also accidentally leaked Hamilton’s plans to attend the 2024 Met Gala in the middle of their hot lap.
‘We have the Met Gala on Monday,’ she yelled, while he spun the car around, doing a burnout on the track.
‘I feel so much better now that it’s over,’ the reality star said as the car came to a stop.
‘I screamed the whole time,’ she told her pals. ‘It was amazing but it was terrifying at the same time.’
The pair, who are both Tommy Hilfiger ambassadors, jetted back to New York in time for the Met Gala Monday.
Hamilton wore a custom Burberry ensemble dedicated to one of the UK’s first Black gardeners, John Ystumllyn, while Jenner stunned in a never-before-worn Alexander McQueen archival dress from 1999.
It followed his sixth place finish at the Miami Grand Prix, which marked fellow Brit Lando Norris’ first F1 victory.
Jenner, for her part, was seen chatting to F1 Academy director Susie Wolff, along with the young women competing in the junior racing series.
Hamilton and Jenner have been friends since 2015, at which time the athlete shot down speculation the two were dating.
‘Me and Kendall have been friends for a while, so we’re just friends,’ Hamilton told E! news in September 2015.
‘She’s doing incredible, she’s very focused, very level-headed, and she’s just — for such a young woman, she’s very grown up,’ he added.
