A woman has had her Facebook account deleted because she shares her name with Kate Middleton.
The social networking site, which you have to be 13 years old or older to join, thought she was pretending to be Prince William's future bride.
The 29-year-old is trying to organise a birthday party but says it's now really difficult because she can't access her Facebook account.
Facebook say they're looking into what happened and are trying to solve the problem.
Kate said: "I logged in and it came up to say I was a fake and my account had been disabled.
"They said I couldn't use my name because I was impersonating someone famous, which I'm not, as I am Kate Middleton."
