Earlier this year, Arnold Schwarzenegger gifted climate change activist Greta Thunberg an electric car, and now it appears that their friendship is going from strength to strength, with the pair recently taking a bike ride together.
In the video below, Geta Thunberg rebukes world leaders for failing to address the climate change emergency:Taking to Twitter, the former Governor of California and strongman shared pictures of himself and the 16-year-old enjoying a bike ride around Santa Monica together before he introduced Thunberg to his 28-year-old daughter Christina.
He captioned the above pictures: "It was fantastic to see my friend and one of my heroes Greta Thunberg last week and go on a bike ride around Santa Monica together and I was so pumped to introduce her to my daughter Christina. Keep inspiring, Greta!"
As part of her mission to change the global climate change emergency, Thunberg has been traveling across the US.
Yesterday, she tweeted: "Since Friday afternoon I've been traveling east through the beautiful southern states in the USA to get to the east coast and hopefully find a transport to COP25 in Madrid..."
While in the US, Thunberg has also met with another famous face and climate change campaigner, Leonardo DiCaprio, who subsequently praised the young Swede on social media.
Taking to Instagram, he wrote: "There are few times in human history where voices are amplified at such pivotal moments and in such transformational ways - but Greta Thunberg has become a leader of our time.
"History will judge us for what we do today to help guarantee that future generations can enjoy the same planet that we have so clearly taken for granted. I hope that Greta's message is a wake-up call to world leaders everywhere that the time for inaction is over. It is because of Greta, and young activists everywhere that I am optimistic about what the future holds.
"It was an honor to spend time with Greta. She and I have made a commitment to support one another, in hopes of securing a brighter future for our planet."
