Kevin Federline fears "the clock is ticking" for his ex-wife Britney Spears

Britney has dismissed the book as "gaslighting" and accused Kevin of "profiting off my pain," saying on Instagram: "If you really love someone then you don't help them by humiliating them."

Speaking to the Daily Mail, Kevin has now rejected those accusations and said he had repeatedly turned down lucrative offers to speak publicly about his ex-wife before now.

He said: "Everybody's concerned about (Britney), right? That's part of the reason why I'm doing this.

"That's why I came out with a cry for help. We've tried to handle things privately for so long that I felt the need to come forward and really try to gain some support for the family, the boys and her. It's just needed. I feel like the clock is ticking."

Kevin and Britney have two sons - Sean Preston, 20, and Jayden, 18 - who live with him in Hawaii and reportedly have little contact with their mother in Los Angeles.

The DJ said their relationship with Britney had deteriorated further since the end of her 13-year conservatorship in 2021, which had placed her finances and personal affairs under the control of her father, Jamie Spears.

Kevin added: "I knew that there's always ups and downs with anybody's life.

"But until my son started coming to me after the conservatorship ended, that's when I write in my book the things that they went through. And I was absolutely shocked and terrified.

"Everybody was worried about her back then and now. That's the thing- nothing has really changed at all. Something needs to happen before something drastic happens."

Asked what kind of intervention might help Britney, Kevin replied: "I don't know. So many things have already been tried. And for me, I don't have all the answers. I just know that I'm not going to sit on the sidelines and do this."

Kevin also insisted: "Look, if this was about money, I could've cashed in a long time ago for a lot of money.

"It's not about that. Family is everything."

He also said he had support from some of Britney's relatives, claiming: "They understand what I'm trying to do because they've been trying to help her too."

Kevin and Britney married in 2004 and divorced in 2007.

Kevin, who also has four other children from previous relationships, said his focus now remains on supporting his family.

He added: "I'm just trying to paint the picture because I feel like it's important for me to tell my truth."
