Britney Spears is apparently finding it difficult to arrange court-ordered drug tests because she is a popstar with an album to promote!! Her lawyer, Anne Kiley, told a Los Angeles judge that the troubled singer fails to answer calls about the tests because she is so busy. Mmmh? I think Splash may have a whole archive of images that proves otherwise! But anyway...Kevin Federline's legal team want his ex-wife to get less visits with their kids, because she keeps missing the random drug tests. Sounds fair enough to me.
