fiance to become Brit's co-conservator

…BABY, ONE MORE THING: Jason Trawick, Britney Spears’ fiancé, was approved as co-conservator of his future wife’s affairs yesterday by a judge in L.A., joining his future father-in-law Jamie Spears, the N.Y. Daily News reports. “Jamie is thrilled,” the elder Spears’ lawyer Geraldine Wyle said after the closed-door afternoon hearing. “It’s all in the family.” Wyle said it was Britney who requested that Trawick take the reins. Trawick and Spears have been dating since 2009, and he popped the question late last year after previously acting as her agent. In his new role as co-conservator, Trawick will have shared control over all of Britney’s major personal decisions, from finances to medical care. That includes the $15 million deal she’s reportedly negotiating to become a judge on The X Factor. Britney has been under court supervision since February 2008, when her dad intervened during her meltdown. (4/26a)
