Britney Spears told her mom, Lynne Spears, to “go f–k” herself after she issued an apology to the pop star.

The “Toxic” singer reflected on her years of medical treatments and “psych ward” stays in a candid Instagram post

The “Crossroads” star, 40, claimed that years would “go by” and her father, Jamie Spears, would still have her locked up

Not one mother f–king person stood up for me !!! Mom take your apology and go f–k yourself !!!” she concluded.
