UNICEF just launched the #Imagine project as part of celebrations for the twenty-fifth anniversary of the Convention on the Rights of the Child. In the powerful video, celebrities were joined by non-celebs in covering John Lennon's iconic anthem, "Imagine". Stars like Katy Perry, Suki Waterhouse, Cody Simpson, Scott Foley and more lent their voice to the cover in hopes of bringing awareness to children's rights.

“The #IMAGINE project gives people across the globe a chance to join a global movement for children, lending their ideas, their visions and, not least, their voices to advance the rights of every child, everywhere,” UNICEF executive director Anthony Lake said in a statement.
