Susan Boyle is suing her brothers after they made allegations about her mental stability.
Reports in the British press say she is suing Gerry and John Boyle for breach of privacy after they gave an interview expressing concern about her alleged bizarre behavior, claiming they were frozen out of all decisions about her.
They were very critical of her management team, headed by two of her nieces and Irish businessman Ozzie Kilkenny.
Her team, however, alleges that some members of the Boyle family only began to take notice of Susan after she became famous.
They point out that both brothers have agents who represent them.
Susan, 49, is said to be devastated by the personal nature of the comments about her and to wish for a complete zone of privacy when it comes to family matters.
