Britney talks about being 'alienated' during tough time

Britney Spears felt "alienated from the public" when she went through a tough time in her life.

The 32-year-old pop star - who exhibited erratic behaviour, including shaving her head, between 2007 and 2008 and was placed under a conservatorship - has recalled feeling so harangued by paparazzi photographers, who would follow her every move, she didn't want to leave her house for nearly two years.
