Britney Spears seems to be taking her recent custody woes seriously. The singer, who was ordered by the court to take drug tests, has been passing with flying colors, according to her lawyer, Sorrell Trope. He states that Brit's taken more than one random test and they've come up negative. It's a step in the right direction toward regaining custody of her sons, Sean Preston and Jayden. Britney also appears to be complying with her court-mandated sessions with a parenting coach. "As far as I know, there have been no complaints," added Trope. Britney's next custody hearing is on October 26.
