Keke Palmer, a former Disney star and the world's youngest talk show host, has become the latest celebrity to be exposed in the ongoing online nude leak scandal.

Half a dozen explicit images showing the 21-year-old actress and singer in various states of undress surfaced online on Friday morning.

In one image she is seen topless and in another she is shown sitting naked on a toilet seat.

The invasion of Palmer's privacy comes weeks after hundreds of celebrity nudes were leaked online following a hack of Apple's iCloud that has come to be referred to as 'The Fappening'.

Although Palmer has yet to comment on the leak, fellow victim Jennifer Lawrence recently branded it a sex crime.

"It is a sexual violation. It's disgusting. The law needs to be changed, and we need to change," Lawrence told Vanity Fair magazine.

"Just because I'm a public figure, just because I'm an actress, does not mean that I asked for this. It does not mean that it comes with the territory.

"It's my body and it should be my choice, and the fact that it is not my choice is absolutely disgusting. I can't believe that we even live in that kind of world."

Scores of intimate images of stars including Kate Upton, Rihanna, and Kirsten Dunst first surfaced on 4chan and Reddit at the end of August 2014, and quickly went viral via social media.

Apple has since vowed to tighten its iCloud security and the FBI is on the hunt for the hackers.
