The conservator of Britney Spears’ personal affairs, Jodi Montgomery, has backed moves to have the singer’s father removed from his position overseeing his daughter’s estate. In a legal filing, Montgomery also claims that Spears’ doctors agree that this is the best course of action.Earlier this week, Britney’s new attorney Mathew Rosengart filed a request to remove Jamie Spears from the conservatorship that has run his client’s financial and personal affairs since 2008.
