Britney Spears' lawyer is going after Kevin Federline for being mean to her and posting videos of family matters. Attorney Mathew Rosengart made a statement. It was cruel for K-Fed to post old footage of Britney arguing with boys. According to Britney's lawyer, K-Fed violated the singer's privacy and dignity, undermined the children, demeaned himself as a father, and violated society's expectations. It's important to remember. Britney and K-Fed are going back and forth in public over her relationship with the kids, with Kevin posting the videos and giving an interview to DailyMail. He says he won't allow Britney to be bullied like she was during her conservatorship. Kevin should keep their family matters out of the public eye according to Britney's lawyer. Britney went public with her children on Wednesday, calling them "hateful" and suggesting K-Fed's house is a marijuana den. The bottom line for Britney's camp. It's not possible to say about K-Fed that she's beloved and respected by millions.
