Private pictures of the 22-year-old star on vacation with Kendall Jenner last December recently surfaced online, supposedly after someone targeted Anne Cox, and Gemma has now hit out at the betrayal, reported Female First.
"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)," she wrote.
When one follower asked "Who cares?", the 25-year-old writer replied, "I do."
They also confessed they were willing to go to prison in return for leaking the private images.
Their account has now been suspended. A number of fans slammed the hacking.
