Leaving her haute couture in her hotel room, the model-cum-actress slipped into a bubblegum pink boiler suit to join McClaren driver Jenson Button before the big Formula One Grand Prix race.
But before the drivers donned their helmets and went head-to-head on the tarmac, Cara got to take a turn in the racing car seat herself, although we don't think she got to turn the key in the ignition (if that's even how those things work).
And Cara wasn't the only model to make the journey from Cannes to Monte Carlo (well, it is only a hop skip and a jump away), with fellow model and BFF Kendall Jenner, Hailey Baldiwin, Gigi Hadid and her sister Bella also stopping by to show Lewis Hamilton some love… Look away now Nicole Scherzinger.
While Cara was in her TAG Heuer shorts and vest, Kendall brought the glamour to proceedings in a scarf-print Zimmerman jumpsuit, oversized shades and a Mercedes Benz cap.
Cara's sister Poppy Delevingne was also at the track, looking summer-ready in a laid back peplum vest and flared jeans, alongside her husband James. If their's a family and friends holiday we'd like to be on, it's definitely this one...
