Private pictures of the One Direction hunk on vacation with Kendall Jenner last December recently surfaced online, supposedly after someone targeted Anne Cox, and Gemma Styles has now hit out at the betrayal.

After Anne closed her Twitter page, Gemma slammed fake accounts which sprang up.

She posted: "Please note: my mum is not back on Twitter, any new accounts are fake.

"To those making them--has her life not been violated enough for you?

"Sadly for the people apologizing there are also opportunistic, nasty people adding insult to injury (sic)"

When one follower asked "Who cares?", the 25-year-old writer replied: "I do."

A person - who goes by the Twitter username @haarrystyles - came forward to claim responsibility for hacking the account and stated they had access to the Harry's fresh solo music.

They also confessed they were willing to go to prison in return for leaking the private images.

They said: "IF I go to jail I did this for all the Harry STANS who don't get s*** from Harry (sic)"

Their account has now been suspended.

A number of fans slammed the hacking.

One wrote: "Which account hacked Anne's iCloud? Who do I have to fight? GIVE MY BOYS AND THEIR FAMILES SOME PRIVACY(sic)"

Another posted: "How disrespectful can you get? Hacking into Anne's iCloud..have some respect for people's privacy and personal life. So rude."
