Though he claimed to be her new manager for a time shortly before her conservatorship was established, the Spears family never quite trusted him.
Both of the megastar's parents claimed in court that he was negatively influencing their daughter, along with criminal allegations that he drugged her, cut her phone lines so that she could not communicate with them, and that in he general took control of "her life, home and finances".
Despite all of the controversy surrounding him, the former manager seemed to be genuinely upset by the "Baby, One More Time" singer's emotional pleas to the judge in her shocking statement on June 23.

He took to Twitter to apologize to Spears saying, "Just sitting here listening to that court recording, if she hates me after she's free I won't blame her..."
"I failed her," he went on. "I was supposed to protect her from all this, I let her down and we both paid dearly for it - - head in hands..I'm so sorry".
It is likely that the "Circus" singer doesn't have warm feelings for her former manager.
She first obtained a restraining order against him in 2008, and recently renewed it again in 2019, claiming that his past actions towards herself and her family caused her "severe mental trauma."
Spears has yet to comment on Lutfi's apology.
