MAX VERSTAPPEN and Kelly Piquet celebrated four years together after packing on the PDA at the US Grand Prix.
The model, 35, has been dating three-time F1 world champion Verstappen, 27, since late 2020.
The two were pictured sharing a passionate kiss in Texas after the Dutch champion came third.
And Kelly took to Instagram to celebrate their anniversary as she posted a bikini picture next to Verstappen, who also soaked in the sun.
The Brazilian is the daughter of three-time F1 champ Nelson.
Although she was born in Germany to her Brazilian dad and Dutch mum Sylvia, Kelly spent much of her childhood in France.

And Verstappen is not the only racer she has dated having been in a relationship with Russian Daniil Kvyat.
The pair began dating in January 2017 and have a daughter together, Penelope, months before they split up in December 2019.
And around a year later, Verstappen entered into a relationship with Kelly, going Instagram official in January 2021.
Ironically, Verstappen actually replaced Kvyat at Red Bull in the second half of the 2016 F1 season.
