Britney Spears has criticised "false tabloids" for publishing stories about her private life.

She says she is infuriated with stories claiming she's having marital problems with husband Kevin Federline and the constant speculation over whether or not she's pregnant.

She posted a letter to a number of publications reports IMDb.com.

She said: "As you read this letter, I bet you are asking yourself: Who? Who, me? Am I a false tabloid? Well, I don't know. But after this posting, I hope you are asking yourself a lot of questions. Your employees are a reflection of your magazine.

"Do you, Us Weekly, In Touch, Star and other desperate magazines want employees who are honest, or those who are liars? It seems to me that you'd prefer the latter. I'm really concerned about the people you hire to work at your companies. I'd like them to ask themselves the question, 'What am I lying to myself about?' Is it that you are 50 pounds overweight? Is it that your children aren't making wise decisions? Or is it maybe that your husband or boyfriend is cheating on you? Until you face what is going on in your life, I guess you'll remain a false tabloid."
