Britney Spears points out ’scary’ details after ex claims she'd stand 'silently' in sons' rooms at night 'with a knife in her hand'

Britney has again hit back at her ex husband as he continues to make claims about the pop star, their relationship, and her acts as a mother.

Pop music sensation Britney Spears is currently in a war of words with her ex-husband Kevin Federline, who she shares two children with, Sean Preston, now 20, and Jayden James, 19.

Federline makes many bold claims in his memoir and one is so damning that Spears has furiously hit back at him. He said she would sometimes enter their sons' bedroom while holding a knife and watch them sleep silently.

In the book, he wrote: “They would awaken sometimes at night to find her standing silently in the doorway, watching them sleep - ‘Oh, you’re awake?’ - with a knife in her hand.

“Then she’d turn around and pad off without explanation."

Britney quickly snapped back at these claims and insisted that her former partner was a part of the reason she had a complex relationship with her children.

Federline has continued to do interview to help promote his book and a conversation he had on CBS Mornings on October 16, resulted in a lengthy and heated response from Spears again.

Posting on Twitter, Spears argued that it was ‘scary’ how convincing her ex was being and insisted that Federline is angry and attempting to humiliate her rather than help her because he cares about her wellbeing, as he has previously stated.

She also insinuated that Federline is making these claims simply to make money, as she is no longer paying child support for her now adult children.

In part, her message read: “To be loved unconditionally and with a naive heart like mine, always being threatened or made to believe I'm the bad one as they profit off my pain…

“The way he is literally attacking me in his interviews. If truth be told the man in the interview went STRAIGHT TO the SOURCE and said it CLEAR AS DAY … no money from Britney for 5 years you trying to get paid that's what general America is saying weird you both have moved on… your kids are adults it's a different world now ... why is HE SO ANGRY ... and what's scary is he’s convincing.

“It literally blows my mind the moments he stops before he cries are you f****** serious … I know his book will sell loads more than mine. If you really love someone then you don’t help them by humiliating them. What scared me was how serious and angry he got, people have no idea, it is way worse than anyone could imagine… the boy hates me and it is deep anger to literally say the things he is saying.”

Spears went on to say she would be focusing on her own healing going forward and spoke about her gardening plans in hopes of finding comfort and enjoying other simple pleasures.
