Emma Watson threatened on nude photo website

Emma Watson is being threatened by hackers just days after making an emotional plea for sexual equality at the United Nations.

In her roleas a UN Women Goodwill Ambassador, the British actressand Harry Potterstar gave an impassioned speech at UN headquarters Saturday, inviting men and boys to join the fight to end gender inequality:

"I want men to take up this mantle," Watson urged. "So their daughters, sisters and mothers can be free from prejudice but also so that their sons have permission to be vulnerable and human too."

Then, hours after Watson told the UN it's a woman'sright to make choices about herbody, someone created a website threateningthe actress by name.

Ominous message on 4chan

Online perpetrators have created a website called Emma You Are Next with acountdown clock ticking down to something happening in about 4 days.

While the message doesn't say what happens when time is up, it was posted on 4chan, the same image-sharing site thatleaked nudecelebrity photos on Saturday, and earlier this month.

The words "Never Forget, The Biggest To Come Thus Far" appear onthe page below a picture ofWatson apparently wiping away a tear.
