Mathew Rosengart, Britney Spears’ new lawyer, wants to make things happen for the popstar. Outside a court in Los Angeles, Rosengart took some time to share information regarding the singer’s conservatorship battle.According to the lawyer, unless Jamie Spears resigns as co-conservator, his firm will move “aggressively and expeditiously” until he no longer has access to Britney’s finances.“First, I once again want to thank Britney Spears for her courage and for her strength,” Rosengart said.
