Britney Spears pictured in 2017Britney Spears has further responded to allegations made about her by her ex-husband Kevin Federline.Earlier this week, a spokesperson for the singer dismissed Kevin’s claims that their sons would be fearful to stay at their mother’s house as “sensationalism”.In a statement, the Grammy winner’s spokesperson pointed out that the claims, made in Kevin’s new book, coincided with Britney no longer having to pay him child support, and accused the former back-up dancer of “profiting off her”. “All [Britney] cares about are her kids, Sean Preston and Jayden James and their well-being during this sensationalism. She detailed her journey in her memoir,” her rep said in the statement.&
