The FBI has launched an investigation into an alleged hacking incident resulting in half-nude photos of actress Scarlett Johansson being leaked on the Web.

An FBI official told Fox News that they were aware of the alleged hacking incident and will be looking into it.

The photos are reported to have come from the artiste's cell phone, some showing her back framed by a towel and others with her completely topless.

Johansson is one of 50 celebrities who have fallen victim to hacking of cell phones and internet addresses, including Jessica Alba and Vanessa Hudgens.

FBI spokesperson, Laura Eimiller told E News that the FBI were investigating a person or group responsible for a series of cyber intrusions of high profile figures. This would include many devices-could mean a computer, desktop, laptop, iPad, cell phone...intrusions into personal online accounts too, she said

I'm glad our politicians do not declare their assets like ScarletJohansson just did. That shock would be worse than their lies.
