Today’s Earth Day, and while every day is a splendid day to take care of our beautiful planet, we’ve raked up Hollywood’s hottest stars going green … in their swimsuits … just for Earth’s special day !

From Kylie Jenner’s bestie Stassie Karanikolaou to gymnastics star Livvy Dunne, these babes planted their hottest green bikini selfies, but can you guess who is who?!?

This American actress and singer was in a recent Disney live-action film, but she’s put down her apple and picked up this green 2-piece … Do you know who she is?

Leonardo DiCaprio was a big fan of the late Pope Francis — praising his work on environmental issues and recalling a story about their 2016 meeting.

The iconic actor took to Instagram on Monday and posted a heartfelt message, with two photos showing their get together at the Vatican, In one pic, they’re seen shaking hands — in the other, they’re leafing through books together.

Their meeting roughly coincided with the release of the 2016 documentary about climate change, “Before The Flood,” which DiCaprio co-produced. As you know, Leo is a major environmental activist.

In his IG post, Leo highlighted the issue of climate change, calling Pope Francis a “transformational leader — not only for the Catholic Church, but also for environmental reform and activism.”

Leo went on … “[Francis] demonstrated a deep and unwavering commitment to environmental stewardship, most notably through his groundbreaking 2015 encyclical Laudato Si’.”

DiCaprio was referring to the 2015 letter Francis mailed to churches around the globe, which “served as a clarion call for a fundamental shift in how we relate to the planet.”

Leo noted the pope’s strong efforts in getting “individuals, communities, institutions, and world leaders to unite in caring for our common home.” DiCaprio also highlighted his 2016 meeting with Francis, saying it was “enlightening” and “deeply moving” for him to sit with the pope and discuss climate change.

Leo wrapped it up by describing Francis as “one of the most extraordinary spiritual leaders of our time,” and his “legacy will continue to inspire generations of environmentalists around the world.”

Before this girl wearing her hat backwards turned into an American singer, actress and model … she was just daringly touching a cactus in Arizona … but growing up in chilly Chicago, Illinois with her six brothers!

At just 15 years old, this go-getter moved to China to get her music career started — eventually releasing her songs, “Every Day in Between” and “Uh Oh.” She may be pretty like a daisy but you better watch out, because this superhero comes with a powerful shield!

Need one more clue? Her stage name is her father’s first name!
