Jennifer Lawrence, Ariana Grande and Victoria Justice are among the many celebs whose nude photos have been leaked online.

On Labor Day weekend, the A-list celebrities' alleged nude photos were posted on a 4chan message board and eventually landed on Twitter, due to a massive Apple iCloud breach, BuzzFeed reports.

According to Music Times, approximately 75 female celebrities have been targeted in the nude photo hack. Among the 75 are Selena Gomez, Kate Upton, Lea Michele, Hilary Duff, Avril Lavigne, Vanessa Hudgens, Kirsten Dunst and Mary E. Winstead.

Although Ariana Grande's camp has confirmed her photos to be fake, Jennifer Lawrence's camp has confirmed the Oscar winning actress' hacked photos to be real.

However, Lawrence's reps have contacted authorities to take action on the recent scandal.

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

Despite the authorities taking action, a source from revealed that Lawrence is now worried that her nude photos online may hurt her booming career in Hollywood.

"Jen is horrified over this leak and knows that this will possibly effect her upcoming roles," says the source. "She knows that A list stars don't have this type of controversy attached to them and is very much horrified over the whole situation."

In addition to Lawrence and Grande, Victoria Justice and Mary E. Winstead have also come forward to publicly address the scandal.

"These so called nudes of me are FAKE people. Let me nip this in the bud right now. *pun intended*," Justice tweeted on Sunday.

Winstead also retaliated on Sunday and tweeted, "To those of you looking at photos I took with my husband years ago in the privacy of our home, hope you feel great about yourselves."

She then added, "Knowing those photos were deleted long ago, I can only imagine the creepy effort that went into this. Feeling for everyone who got hacked."

The 4chan hacker has yet to be identified.
