Pop star Britney Spears slammed her mother, Lynne Spears, for her conservatorship. “The most dangerous animal in the world is a silent smiling woman,” reads an image Britney, 39, shared via Instagram on Tuesday, November 2.

The “Toxic” singer discussed how she’s been happy a lot recently in the caption. However, she also doesn’t only blame her father, Jamie Spears, for her adult guardianship.

“Pssss my dad may have started the conservatorship 13 years ago … but what people don’t know is that my mom is the one who gave him the idea !!!! I will never get those years back …. she secretly ruined my life,” Britney alleged.

The Louisiana-raised performer called out Lynne, 66, in the post as well as Lou Taylor. The Tri Star Sports and Entertainment Group CEO, 56, was Britney’s former business manager. She no longer works with the family.

“And yes I will call her and Lou Taylor out on it,” Britney added in her caption. “So take your whole ‘I have NO IDEA what’s going on’ attitude and go f–k yourself !!!! You know exactly what you did.”

The Grammy winner says that while Jamie ultimately had legal control of her, he was “not smart enough to ever think of a conservatorship” without Lynne and Taylor.

The popstar first entered the conservatorship in 2008. In September, a judge approved the “Womanizer” singer’s petition to remove her father from his 13-year position as conservator of her estate.
