It's time to bring out the big guns!

The FBI has now come in to investigate the now-infamous celebrity nude photo leak that's been clogging up the Internets for the past few days. The web blew up over Labor Day weekend when an anonymous hacker posted nude and rather scandalous photos of a bevy of celebrities including Jennifer Lawrence, Kate Upton, Victoria Justice, Ariana Grande, Mary-Kate Olsen, Rihanna, Kirsten Dunst and Kaley Cuoco.

On Monday, a rep for the Federal Bureau of Investigation told the Associated Press that the FBI was, "aware of the allegations concerning computer intrusions and the unlawful release of material involving high profile individuals, and is addressing the matter."

While some celebs like kid-friendly stars Ariana Grande and Victoria Justice are trying to distance themselves from the pics, claiming they aren't real, others are confirming that the pics are real and are condemning the stolen images.

Jennifer Lawrence's rep said, "This is a flagrant violation of privacy. The authorities have been contacted and will prosecute anyone who posts the stolen photos of Jennifer Lawrence."

Kate Upton's lawyer released a statement saying, "This is obviously an outrageous violation of our client Kate Upton's privacy. We intend to pursue anyone disseminating or duplicating these illegally obtained images to the fullest extent possible."
