For the past 13 years Britney Spears has been under conservatorship, a legal framework where her dad has had virtually full control of her life and finances. During some of that time, her father hired a security firm to spy on her, both digitally through her phone, and physically with audio recording devices in her bedroom, according to a new documentary by The New York Times. Wednesday, Jamie Spears was removed as his daughter's conservator.

The documentary features a former employee of Black Box Security, the firm hired by Spears' father Jamie.
