Kevin Federline’s brother has claimed that he is the father of his ex-sister-in-law Britney Spears’ eldest son Sean Preston. Christopher Federline made the allegation in court papers filed for a temporary restraining order against the 31-year-old pop star, Radar Online reported. In the papers filed in US District Court in Tampa, Florida, Federline alleged that the X Factor judge blackmailed and harassed him and stole away his credit card withdrawing 4,500 dollars from his bank account. He added that after he confronted her about the theft, Spears allegedly made fun of him. Christopher also claimed that Spears blackmailed him that if he tells the police about the credit card, she will tell the world that he’s the true father of her now-seven-year-old son, Sean Preston, not Kevin. He said that in the recent years, Spears had used their secret to gain leverage over him.
