New claims from documentary
Britney Spears' father has been accused of crossing "unfathomable lines" after a documentary claimed the singer was secretly recorded in her bedroom during her conservatorship.
'Controlling Britney Spears' alleges her conversations with her two sons and boyfriend were taped.
Her legal team say the reports need "serious investigation".
Her father Jamie Spears has not commented.
Two programmes about the 39 year-old's conservatorship are being released today.
Netflix's 'Britney versus Spears' has promised to expose secrets about the legal arrangement, in place since 2008.
While 'Controlling Britney Spears', which lands on Sky Documentaries tonight, features interviews with key insiders and those with first-hand information.
