He told US radio station Power 106FM: "Sean P. I would save my kids. Sorry baby I love you but I had to say that."
The couple - who married in 2004 - had their first child in October and Britney's parenting skills have come under intense criticism.
Social services recently paid their residence a visit after Sean fell out of his high chair and fractured his skull. The 24-year-old singer is now planning to sue the makers of the high chair.
K-Fed's ex and mother of his first two children has reportedly been the star's most ardent critic and told Kevin that Britney should not be left alone with her children.
According to rumors Sean may soon have a new sister or after she was photographed showing a tell-tell belly and publicists refuse to deny or confirm reports.
When asked about the pregnancy rumors K-Fed refused to comment.
He did however go on to reveal details about his wife's unusual cravings for pickles and ice cream during her first pregnancy.
