Alicia Keys just leaked her own nude photo ... for a very good reason.
The singer just posted the above pic, taken by Mark Seliger, on her Instagram page -- showing her 100% naked with a peace sign painted on her baby bump and a hand-bra to preserve her modesty.
How incredible does she look? The 33-year-old is seriously glowing!
"It's you and me on a mission to create a kinder and more peaceful world. The #WeAreHere Movement begins today," she captioned the photo.
Keys went into more detail about her movement with the New York Times, urging fans to donate money to one of 12 different charities, benefiting everything from gay rights to supporting children with HIV and AIDS. Alicia is donating $1 million of her own money to be divided among the 12 organizations.
