Kelly Piquet highlights major environmental crisis
Piquet was previously in a relationship with former Red Bull star Daniil Kvyat from 2017-2019, with whom she shares a daughter Penelope.
The Brazilian frequently shares pictures of Penelope, or ‘P’ as she is affectionately nicknamed, on social media, recently missing out on a New York Fashion Week appearance to support her daughter.
Piquet has also used her social media to promote causes she cares about, including the recent crisis in the Amazon rainforest which is seeing ‘record-breaking’ fires.
She re-shared a reel via her Instagram page from @earthlyeducation, that depicted the disastrous impact deforestation and climate change is having on the region and its inhabitants.
"The Amazon is on fire. This catastrophic situation deserves global attention - the international community must care, and act. Protecting the Amazon in a massive climate solution. We need a @fossilfueltreaty," the caption underneath the post read.
Piquet has previously demonstrated her passion for environmental causes, and has used her platform to support sustainability and to fight plastic waste.
In 2023, Piquet collaborated with Opp Swimwear and Plastic Bank, where they succeeded in ‘diverting 256,747 plastic bottles’ from the ocean.
