Kim Kardashian is never shy of sharing a selfie, and on Wednesday it was one with a deeper meaning - to draw attention to the dangers to the environment.
The reality TV star posted a bikini snap captioned: 'In honor of Earth Day here is my best plant selfie from my new book #Selfish coming out May 5th! .
The 34-year-old, who recently treated herself to a $407,000 2015 Rolls Royce Phantom, is seen taking the photo in a mirror wearing a skimpy white bikini, in front of a lush greenery.
Her sister Kourtney also got in on the act, posting an Instagram snap underneath a huge tree.
Wrapped in a white bath robe, the 36-year-old television personality captioned: 'Happy Earth Day! Let's take care of her. ??????'
Uptown Girl Christie Brinkley also showed her support on Instagram for Earth Day, with an adorable tree-hugging snap.
The stunning 61-year-old model stuck a face on the tree and captioned the snap: 'It's Earth Day ! Hug a Tree!
In a second shot, the model is seen skipping through a green field with a floral CND symbol, alongside her two white dogs.
She captioned the snap, 'I wish all sentient beings PEACE on Earth Day!
