Britney Spears says she has been praying as she prepares for a crucial court hearing which could bring the termination of her conservatorship.

The pop superstar could regain control of her personal life and finances on Friday when a judge in Los Angeles hears arguments to end the complex legal arrangement she has been under since 2008.

The 39-year-old scored a significant victory in September when her father was suspended from his role overseeing her money.

Jamie (69) has since called for the conservatorship's immediate termination, though his daughter’s lawyer has accused him of attempting to dodge difficult questions about his work on the arrangement.

Spears has been vocal on social media in recent weeks and in a since-deleted post said her mother Lynne "seriously ruined" her life.

She returned to Instagram days before the next court hearing and told her 35 million followers "I haven’t prayed for something more in my life".

Spears said: "This week is gonna be very interesting for me !!! I haven’t prayed for something more in my life !!! I know I’ve said some things on my Insta out of anger and I’m sorry but I’m only human … and I believe you’d feel the same way if you were me !!!

"Anyway it’s a new day and I can’t say I’m never going to complain again … cuz who knows !!! God bless you all and have a great day !!!"
