Britney Spears has announced she is pregnant, months after she escaped the legal arrangement that gave her father control over many aspects of her life. The singer told her 40 million Instagram followers she was having a baby with partner Sam Asghari. The 40-year-old, who has two teenage sons, also revealed she suffered depression during a previous pregnancy. In June last year, she told a judge her conservatorship prevented her from marrying or removing her birth control. She has previously said she wanted a family with Asghari, a 28-year-old personal trainer. But the form of legal guardianship known as a conservatorship, set up by her father in 2008 after she experienced a public mental health crisis, meant she could not make her own decisions about her medical care.
