Federline, a former backup dancer who was married to Spears from 2004 to 2007, spoke to ITV this week and said the former couple’s two teenage sons had decided not to meet their mother. On Wednesday, Federline posted old videos on his Instagram account where Spears appeared to be arguing with her sons, 11 and 12. In response to the videos, social media users reacted bewildered, saying Spears appeared to reprimand her children, as any parent would.

Spears, who terminated her custody in November after more than 13 years, said she was “sad” that Federline would discuss her relationship with her two sons publicly.

Now, Spears’ attorney, Matthew Rosengart, says Federline violated his client’s privacy and created possible legal problems for himself. Rosengart said he is working with Instagram to ensure Federline follows its rules.

“Britney Spears was a brilliant and extremely hardworking icon, rightfully loved and respected by millions around the world. Unfortunately, the same cannot be said for Mr Federline, for inexplicable reasons The decision to conduct an unprovoked interview hurts the mother of his child,” Rosengart said in a statement type.

“Britney has been loyal to her children and she loves them so much,” the statement continued. “Whether he realizes it or not, Mr. Federline violated not only the privacy and dignity of his children’s mother but also the privacy of his own children, which he should protect. His ITV interview aside, Mr. Federline The ill-advised decision to post an old video of his 11 and 12-year-old kids is cruel and downright. It’s abhorrent.”

“In addition to belittling himself and violating social norms, he has now created a variety of legal problems for himself, including but not limited to being implicated in online harassment and cyberbullying statutes,” Rosengart wrote.

“I am honored to work with Britney to suspend her father’s custody, to help her gain freedom and dignity, and to help protect her from past bullying – we will not tolerate bullying anywhere,” Hollywood attorney said the former federal prosecutor.

“We are working with Instagram to ensure Mr. Federline follows its rules and we are exploring all appropriate remedies for him,” Rosengart said. “At the same time, as Britney poignantly said, whatever happened between her and her children should be kept secret. We urge Mr. Federline to act with grace and dignity and to stop publicly revealing private affairs, it’s not good for anyone.”

As of Thursday morning, Federline’s video had been removed. Federline originally posted the videos on Wednesday night, claiming he did so in support of his teenage son.
