Little Dicky Releases His Celebrity Driven 'Earth' Single

Lil Dicky just released his single "Earth" and it' features about everyone in entertainment from Justin Bieber to Leonardo DiCaprio.

The song -- a call to action to help save the planet -- features a lengthy animated music video with celebs as plants, animals and even diseases with the chorus, "We love the Earth, It is our planet."

Bieber is the first celeb appearance, playing a baboon and singing the lyrics, "Hi, I'm a baboon, I'm like a man just less advanced and my anus is huge." The song is both silly and has a purpose of uniting people ... urging listeners to value their neighbors and take steps to stop climate change.

The animation is pretty impressive ... Ariana Grande is a zebra, Halsey a lion cub, Wiz Khalifa a skunk, Snoop Dogg a weed plant, Adam Levine a group of vultures, Shawn Mendes a rhino and Ed Sheeran lends his voice to a Koala ... just to name a few.

Some notible features include Kevin Hart as Kanye West and Lil Yachty HPV cells. DiCaprio plays himself and dubs "Earth" the best song he's ever heard.
