She writes in an excerpt obtained by People: ‘It was a surprise, but for me, it wasn’t a tragedy. I loved Justin so much. I always expected us to have a family together one day. This would just be much earlier than I’d anticipated.

‘He said we weren’t ready to have a baby in our lives, that we were way too young. I’m sure people will hate me for this, but I agreed not to have the baby.

‘I don’t know if that was the right decision. If it had been left up to me alone, I never would have done it. And yet Justin was so sure that he didn’t want to be a father.’

The star claimed while she wanted the baby and ‘dreamed of having a family’ with Timberlake, he ‘wasn’t ready’ for the responsibilities of parenthood and thought the pair were too young.

The star said the abortion was ‘one of the most agonizing things I have ever experienced in my life’ in the memoir – set for release on October 24.

It was also claimed in the book Spears reveals she was raised ‘not to get an abortion’ due to religious reasons and what she had learned from her family, reports TMZ.

DailyMail.com has contacted representatives for Timberlake, Spears and Simon & Schuster for comment.

Spears would later welcome sons Sean Preston, 18, and Jayden, 17 with Kevin Federline while Timberlake shares sons Silas, eight and Phineas, two with wife Jessica Biel.

In 2021 Timberlake apologized to Spears for his past treatment of her

This comes amid claims Timberlake is ‘concerned’ over what ex Spears’ upcoming memoir – The Woman In Me – will reveal about their past romance, according to a new report,

The SexyBack hitmaker is said to be ‘very curious’ about the star’s memoir, which will be released on October 24.

A source told Page Six: ‘He’s very curious what she’ll reveal from their relationship. It’s eating at him.’

A publishing insider also denied the book was a ‘takedown’ of anyone, saying: ‘This is Britney finally getting a chance to tell her empowering story and it’s nothing more than that.’

Justin and Britney dated as teenagers after meeting at The Mickey Mouse Club and were an iconic star duo.

They split abruptly in 2002 and rumors soon emerged that she’d cheated on him.

His career soared. Albums and songs were promoted under the narrative that Spears broke his heart. In the music video for his 2002 hit Cry Me A River, he even used a Britney lookalike. Britney was vilified for their break-up.

In 2018 Timberlake said he was so emotional following his split from Spears that he unloaded his feelings by writing Cry Me a River in just two hours.

The former teen heartthrob’s hit song has long been rumored to be about the pop princess, following claims she cheated on him.

The star wrote of the breakup ballad: ‘I’ve been scorned. I’ve been p***ed off. The feelings I had were so strong I had to write it.

‘I translated my feelings into a form where people could listen and hopefully relate to it. People heard me and they understood it because we’ve all been there.’

Timberlake didn’t mention Spears by name in his book but made clear he was a changed man, crediting wife Jessica and  son Silas for his transformation, he wrote in Hindsight: And All The Things I Can’t See in Front of Me.

In the tome, Timberlake insisted his most defining moment has been becoming a father to son Silas, who was born in April of 2015, writing: ‘Having a child has been the pinnacle of my life.’

Timberlake writes when he first saw his son: ‘I had such intense feelings – nothing that I’ve ever experienced can compare to it.’

In 2021 Timberlake wrote in an open apology that he was ‘deeply sorry’ and would ‘take accountability’ admitting that he had ‘failed’ her, after their relationship came under fresh scrutiny following the release of documentaries looking into Spears’ conservatorship.

In a Instagram post, Timberlake said: ‘I specifically want to apologize to Britney Spears and Janet Jackson both individually, because I care for and respect these women and I know I failed.’

Timberlake’s apology comes after he was tagged in social media posts about Spears and the campaign to release her from a conservatorship held by her father.

It has been highlighted in a documentary, Framing Britney Spears, which lays bare how Spears has, according to her fans, been exploited by the men in her life.

In a 2002 interview with Diane Sawyer, Sawyer asked Spears: ‘He’s gone on television and pretty much said you broke his heart, you did something that caused him so much pain. What did you do?’

In an interview in 2002, Britney was asked by Diane Sawyer. 'He's gone on television and pretty much said you broke his heart, you did something that caused him so much pain. What did you do?'  She broke down in the interview after saying she was 'hurt'

Crass: Timberlake didn't shy away from speaking about their relationship post-split - in one example, he was asked: 'I have to ask, did you f**k Britney Spears?' He laughed, sighed, then said: 'Oh man, OK I did it' (pictured 2002)

Britney, then 21, replied: ‘We’re both really young. It was kind of waiting to happen. I will always love him.

‘Everyone has a side of their story and to make them feel a certain way, make them feel, you know… I’m not saying he’s wrong and I’m not saying he’s right either.’

Timberlake didn’t shy away from speaking about their interview. In one example, he was asked: ‘I have to ask, did you f**k Britney Spears?’

He laughed, sighed, then said: ‘Oh man, OK I did it’.

In an interview with The Telegraph in 2002, he also said: ‘The break-up was absolutely heartbreaking for me.

‘I can’t just have meaningless relationships with women. I have to find Miss Right in order to have a relationship. There’s got to be that big moment when she comes along.’

Spears’ book will also go into detail about the longtime conservatorship Spears lived under that father Jamie Spears controlled from 2008 until 2021.

The book’s summary reads: ‘A brave and astonishingly moving story about freedom, fame, motherhood, survival, faith and hope’.

Spears announced she was writing a book in February of 2022 in an Instagram post.

‘Well I’m writing a book at the moment and as it’s actually healing and therapeutic… it’s also hard bringing up past events in my life … I’ve never been able to express openly!!!’ she said.

The Toxic artist addressed fans on the status of the forthcoming tome, as well as the delays, via social media this past May.

‘I almost feel like my life in the business has always been that girl at school who was bullied and laughed at!!!’ she said. ‘But in my case there is no superior person to set it straight!!!’

She continued: ‘I think some people are wanting to hear my story … either through a book or what have you??? I’ve had to stop a couple of times!!! It may take me a year, maybe longer who knows … to share my story !!!’

Spears has hired Oscar-nominated actress, Michelle Williams, to narrate the audiobook for her upcoming memoir titled.

The Baby One More Time hitmaker, has recorded a small portion of the book and avoided narrating chapters discussing her family due to the content being ‘too painful to retell,’ TMZ recently reported.

In a statement published on Friday, the performer expressed, ‘This book has been a labor of love and all the emotions that come with it.’

Spears continued, ‘Reliving everything has been exciting, heart-wrenching, and emotional, to say the least. For those reasons, I will only be reading a small part of my audiobook.’

The star then gushed, ‘I am so grateful to the amazing Michelle Williams for reading the rest of it,’ with The Fabelmans actress, 43, also telling the outlet in support of the songstress, ‘I stand with Britney.’

Insiders also explained that the star chose to not narrate chapters that discuss her family ‘because she found them too painful to retell in her own words.’

Initially – the publisher Gallery Books, an imprint of Simon & Schuster – had aimed to get Legally Blonde actress Reese Witherspoon to take part in the audio recording of the book. However, she was not ‘available’ to take on the job.

In the past: Back in August, Spears' husband Sam Asghari notably filed for divorce from Spears after a little over one year of marriage (pictured 2018)

Back in August, Spears’ husband Sam Asghari notably filed for divorce from Spears after a little over one year of marriage. He cited ‘irreconcilable differences’ as the reason for the split and is asking for spousal support from the performer, as well as coverage for his legal fees.

Due to an ‘iron-clad prenup,’ Sam will not profit on her upcoming memoir. He is mentioned in the book, but ‘not a lot,’ a source recently told DailyMail.com.

However, sources told TMZ that the singer made ‘some changes’ to the memoir following their separation.

When she spoke out about the divorce for the first time since the divorce news came to light, Britney admitted that she was ‘a little shocked’ but ‘couldn’t take the pain anymore…’

The star later expressed that she would focus on staying ‘strong’ and concluded with, ‘And I’m actually doing pretty d**n good!!! Anyways have a good day and don’t forget to smile!!!’

Asghari has previously claimed that Britney had gotten ‘physical’ with him on various occasions during the course of their relationship. The pair notably first met on set of her 2016 music video, Slumber Party.
