UPDATE: A bizarre lawsuit filed in Florida concerning the paternity of Britney Spears' child has proven to be a fraud, and the man who filed it is in hot water over more bogus claims concerning the Newtown, Connecticut school shooting.
A lawsuit filed in Tampa claimed that Christopher Federline, the brother of Britney Spears' ex-husband Kevin Federline, was the actual father of the pop star's first-born son Sean Preston.
The person who filed it, however, was Jonathan Lee Riches, who has become notorious for filing thousands of lawsuits, which are typically dismissed. He even has his own Wikipedia entry detailing many of his filings.
It was another phony claim that has since landed Riches back in jail, however. The Smoking Gun reports Riches was arrested by the feds for violating his probation when he traveled to Newtown, Connecticut, where he claimed he was the uncle of Sandy Hook Elementary shooter Adam Lanza.
Riches was reportedly serving a five-year federal probation term, which prohibited Riches from leaving Pennsylvania's Eastern District judicial boundaries without permission from a judge or his probation officers.
Cape Coral, Florida -- The brother of Kevin Federline has filed a restraining order against Britney Spears and in it claims he is the true father of her first born, Sean Preston.
In the court document, Christopher Federline confesses he and Britney slept together and that he is the "true father of Sean Preston". He petitioned for the restraining order on Dec. 18 after he says she stole his credit card while she was picking up her son's Sean and Jayden at his brother, Kevin's house.
Christopher says Britney grabbed his wallet while it was on the coffee table and stole his Capital One credit card and used it to buy over $4,500 worth of comic books for her children through Comic Conquerors' website.
When Christopher became aware of the purchases - which included a MAD magazine, and Betty Boop and Archie comics - he called the owner of the company, Charles Nunez, who told him Britney is a longtime customer and would not give him a refund.
He said he then called Britney who "made fun of me and told me I have a small penis and also blackmailed me and told me if I tell the police that she stole my credit card that she will tell the world I'm the true father of Sean Preston, not Kevin."
Christopher - who has no job, no money and no assets - then ended the petition by saying he is seeking the restraining order against Britney because she is "out of control and a maniac".
