He also told NOTW how she kept Jayden James and Sean Preston up late so they would sleep through the mornings and not wake her.

If they woke early, a member of staff dealt with them.

Tony said: "Britney does love her kids but she is a fickle mum. When the kids are happy, she's happy. When they're crying or unwell, she's not sure what to do.

"She speaks to them in weird, creepy, baby voices, in made-up languages, which they just don't get. All it does is unsettle, upset and scare them. Often she would scream and cry uncontrollably. Imagine what that is like for young children."

Tony said he never saw her feed the boys. He added: "When they are unwell, her answer is: ‘Give the baby a bottle of medicine.' I've never seen her deal with them like a full, attentive mum."

Tony knew he had to take action when Britney nearly wrote off her car with the kids inside. He said: "We followed her but she was driving like a lunatic on the wrong side of the road. It was terrifying."
