US pop star Britney Spears has announced her engagement to her long-term boyfriend, Sam Asghari. The singer posted a video of the couple showing off the ring on Instagram. The 39-year-old is fighting a legal battle to end her 13-year conservatorship, which controls both her personal life and finances. Spears has revealed that the terms of the arrangement are preventing her from marrying Mr Asghari, 27, or having more children. The conservatorship arrangement was imposed in 2008 when concerns were raised over her mental health.
