As the team continues to look forward and focus on the future, Rosengarttold PEOPLE after last week’s hearingthat he will be focused on “communications between Jamie Spears and Jamie Spears' counsel, and we will go where the facts lead us.”
“Respectfully, the court was wrong to suspend Mr. Spears, put a stranger in his place to manage Britney’s estate, and extend the very conservatorship that Britney begged the court to terminate earlier this summer,” Thoreen wrote in a statement, before adding, “Despite the suspension, Mr. Spears will continue to look out for the best interests of his daughter and work in good faith towards a positive resolution of all matters.”
In court on Wednesday, Thoreen also insisted that Jamie has made all decisions in his daughter’s “best interest.”
