** IMAGES IN THE GALLERY ABOVE SHOW NUDITY AND ARE NOT SAFE FOR WORK OR KIDDIES**

Another day in the entertainment world, another nude-celebrity-cell-phone-photo scandal.

Over the weekend semi-naked mobile phone pictures were leaked of Jessica Alba and Kat Dennings (Dennings pics are here, link NSFW).

In Jessica Alba's case, it seems that the photos were taken for partner Cash Warren to show off her pregnant stomach.

Apparently the 'leaked' Kat Dennings pics were a deliberate publicity stunt. Ho-hum.

So, here's a hot tip. If you're a celebrity, AVOID TAKING NUDE PICS OF YOURSELF IF YOU DON'T WANT THEM LEAKED. While we understand sexting is becoming a bit of an issue with teenage kiddies who don't know any better, surely if you're in the public eye you understand than nude pics of yourself are hot property and thus become dangerous if they fall into the wrong hands?

Nothing is safe in the world of modern technology. Mobile phones get lost, relationships break up and jilted lovers seek revenge. Boffins can also hack email and mobile phone accounts. Those pictures can come back to haunt you.

Celebs who have learned this lesson the hard way include Rihanna, Lily Allen, Lara Bingle, Vanessa Hudgens and Kanye West.

We've posted some of the leaked pics in the gallery above this post. You may need to bathe in holy water after viewing.
