There's nothing like letting off a bit of steam at a party, and that is exactly what Scarlett Johansson did with her good friend Justin Timberlake amid an alleged hacking scandal where photos of the actress leaked on the Internet.

Scarlett Johansson was spoted at the 1OAK nightclub in NYC, partying with Timberlake until dawn, according to life and style magazine. The two were seen arriving at the club at around 3am, and dancing until 5am.

Meanwhile, The FBI has launched an investigation into an alleged hacking incident resulting in half-nude photos of the  actress 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
