Britney Spears slammed her 14-year conservatorship in a new Instagram post.

Spears insisted fellow singer Jennifer Lopez would never be treated how she was, writing: “After 14 years of telling me no to what I wanted… it’s ruined for me… but that wasn’t the worst part… the worst part was my family locking me up in that place for 4 months.

“Jesus f**king Christ… I’d like to see somebody tell Jennifer Lopez to sit down 8 hours a day 7 days a week… no car, own security of 5 years telling me at my own door I can’t walk outside for 4 months… no door for privacy… and watched me change naked and shower…” the lengthy post included.

She insisted Lopez’s family “would never allow that,” continuing: “Psss… you say do what you want to do now. Really 14 years later after being humiliated… it’s WAY too late for that… again I’d rather stay home and s**t in my f**king pool than join the entertainment business… the truth is a f**king b**ch.”

In another post, Spears insisted she wanted to remix her music for her fans “to make the songs feel new.”

However, she said she was “told no.”
