Britney Spears revealed that she was completely oblivious that Kevin Federline had a baby on the way when they first started dating, after hitting it off at a club in 2004.

In another shocking revelation from her memoir, The Woman in Me, the pop star, 41, claimed that she was completely in the dark about his former fiancée Shar Jackson’s pregnancy.

‘Kevin had a bad boy image. Still, I had no idea when we met that he had a toddler, nor that his ex-girlfriend was eight months pregnant with his second baby,’ she insisted in her newly-released book.

She continued: ‘I was clueless. I was living in a bubble, and I didn’t have a lot of good, close friends to confide in and get advice from.’

Ultimately, the mother-of-two divulged that she learned the news until they had ‘been together for a while’ and someone asked her: ‘You know he has a new baby, right?’

After initially feeling in disbelief, Spears confronted Federline, who told her about his Kori Madison Federline, now 21, and Kaleb Michael Jackson Federline, 19.

‘You have kids?’ I said. ‘You have children? Not only one child but two children?” she recalled grilling him.

Despite feeling blindsided, the Toxic hitmaker continued to date and wed, later that year.

The former couple went on to welcome two sons of their own, Sean Preston, 18, and Jayden, 17, before calling it quits in 2007.

Amid their contentious split and custody battle, Spears revealed in her new book that she was struggling with postpartum depression.

‘Kevin tried to convince everyone that I was completely out of control,’ Spears wrote. ‘He started to say I shouldn’t have my kids anymore — at all.’

In Spears’ memoir, she also spoke about trading her ‘freedom’ during her controversial conservatorship in order to see her children.

The performer also discussed her ultimately futile attempts to resist the conditions of her arrangement with her father, Jamie Spears, who under the conservatorship had complete control of her assets and worth alongside attorney Andrew Wallet.

Federline was give sole legal and physical custody of their sons in 2008 after Spears was hospitalized, following an incident, in which she locked herself in a bathroom with her sons and refused to turn them over to Federline

‘My freedom in exchange for naps with my children — it was a trade I was willing to make,’ she wrote via People.

She added: ‘Starting a family was my dream come true. Being a mom was my dream come true.’

The singer also spoke about how she gave up on pushing back against the control of her father after she went through two involuntary psychological assessments.

‘After being held down on a gurney, I knew they could restrain my body any time they wanted to. And so I went along with it,’ she recalled.

Spears went on to express that she viewed the conservatorship as a particularly dark period in her life.

She wrote: ‘Thirteen years went by with me feeling like a shadow of myself. I think back now on my father and his associates having control over my body and my money for that long and it makes me feel sick.’

Spears’ controversial arrangement, which began in 2008, was ultimately ended in November of 2021.

Britney and Kevin’s relationship was chronicled in the reality program Britney and Kevin: Chaotic, which aired for a single season in 2005.

The couple announced their engagement, which occurred after just three months of dating, in July of 2004, and they held a wedding ceremony two months later

Spears and Federline, 45, went on to welcome Sean in September of 2005, and they added Jayden to their family the following September.

However, the singer filed for divorce that November, and her marriage was formally dissolved in 2007.

Although the two co-parented their children for several years, the former rapper began serving as their full-time caretaker while their mother fought to end her conservatorship.

Federline has since moved to Hawaii with Sean and Jayden, who remain in contact with their mother, although the pair made the decision to stop seeing their mother in early 2022.

In an Instagram video, Spears went on to admonish her kids for ‘making the claims that “she’s not good now” and “she wants attention.”

Spears’ Instagram rant came after her sons spoke out about their relationship in a 60 Minutes interview.

Jayden said during the interview that there is ‘no hate’ towards his mother, but he said, ‘it will take a lot of time and effort’ to repair their fractured relationship.

‘I 100% think this can be fixed. It’s just going to take a lot of time and effort. I just want her to get better mentally. When she gets better I really want to see her again. ‘

Speaking directly to their mother, he adds: ‘I love you a lot, I hope for the best for you. Maybe one day we can sit down like this and talk again.’

Britney shocked her fans when she testified in June 2021 that her conservatorship, which was put in place in 2008, prevented her from getting married or even having another child.

‘I want to be able to get married and have a baby,’ she said during a conservatorship hearing in 2021.

‘I was told right now in the conservatorship, I’m not able to get married or have a baby, I have an IUD inside of myself right now so I don’t get pregnant.’

Her wish was granted six months later, in November 2021, when a judge officially terminated the conservatorship.
