Demi Moore claimed her daughter's ex-partner and father of her child exhibited 'aggressive' behavior as she gave birth in a bombshell court declaration this year.

Rumer Willis, 37, welcomed daughter Louetta, now three, with Derek Richard Thomas in April 2023 - but their , with a child custody battle exploding between the pair since July 2025.

In court documents obtained by The Daily Mail, Willis accused Thomas of 'violence and coercive control' - which he has vehemently denied - with Moore claiming in a January declaration that Thomas 'appears to want to dictate and control Rumer’s environment to his needs.'

Moore, 63, claimed this alleged control boiled over when she and Rumer's sisters Scout and Tallulah joined the former couple for the birth of Louetta at home.

Moore alleged in a court filing: 'From the time of my daughter’s pregnancy, I witnessed Rumer under a constant state of stress. She stated often that she was not receiving any sensitivity or support from Derek. 

'Initially I thought it was in part the hormones with the pregnancy occurring on top of this after such a short relationship. Overtime I saw that his behavior was very odd and that he always put himself and his needs first.

'While Rumer was giving birth to Louetta in the birthing tub, Derek, without asking, and without having showered, got into the birthing tub in an aggressive and sudden manner.

'Everyone was shocked. Rumer asked him to get out immediately, and he did. He then spent the rest of the birth acting angry and pouting, and making it all about him.

Moore wrote: 'From the time of my daughter’s pregnancy, I witnessed Rumer under a constant state of stress. She stated often that she was not receiving any sensitivity or support from Derek'

'He wanted to isolate me from my friends and family. He constantly called me a liar with no reason behind it. He told me I was a bad girlfriend all the time. He had paranoid behavior saying that my mother and I were plotting to take Louetta away from him.

Thomas denied all allegations of domestic abuse in documents filed in early 2026, but acknowledged the relationship was 'unhealthy and appropriately came to an end.'

'I have committed no acts of domestic violence in any form, including any active ‘coercive control' adding 'it was not at all characterized by any violence, physical or emotional attacks or intimidation on my part' he wrote.

'The decision to end the relationship between myself and [Rumer] was a mutual decision made in our mutual best interests.'

Willis also alleged in 2026 that Thomas does not pay child support 'nor has he ever offered to pay for anything that Louetta needs.'

She alleged he does not work and earns $3,000 a month from royalties - claiming Thomas expects her and her 'wealthy family to take care of everything financially, emotionally, and physically

Per income and expense documents filed this year, Willis said she made more than $4800 a month with her production company and $4,000 to $5000 a month from her rental property. She spends around $15,000 to $21,000 a month on other expenses such as childcare and groceries.

Willis said she does not rely on her wealthy parents to pay her expenses and 'is no longer willing to support [his] visitation or pay for all of Louetta’s expenses.'

Thomas claimed to make $3600 a month from his occupation as a 'musician, educator and entrepreneur.'

The original petition to determine the parental relationship saw Thomas request an order for child custody and visitation, claiming Willis had permanently moved to Sun Valley, Idaho with Louetta in 2024, without his consent. Willis denies this. 

Thomas requested joint legal and physical custody of Louetta and child visitation - with Willis filing a motion to dismiss his petition in August 2025.

She claimed Louetta's home state was Idaho but this case was itself dismissed in January 2026, with California found to be the correct state, 

Per the documents, Willis claimed he had offered to pay for Thomas to visit Louetta in Idaho and he has allegedly refused.

Thomas' lawyer told the Daily Mail: 'Mr. Thomas is a caring devoted and loving father to Louetta. It is, to put it mildly, unfortunate that Ms. Willis has sought to obstruct Mr. Thomas' relationship with Louetta without justification of any kind whatsoever'

In subsequent court documents, she claimed Thomas was offered a place to stay on Moore's Sun Valley property where Louetta and Willis live, but he allegedly 'forfeited visits.'

The former couple agreed to mediation with a private judge in September 2025. 

Willis asked for primary physical custody and for a custody evaluation as well as drug testing for Thomas due to his alleged 'history of chronic daily marijuana use and evidence of behavior indicative of someone under the influence of drugs for extended periods of time.'

Thomas responded: 'This is false' and 'I have previously used marijuana as legally allowed and at no point did I engage in the use of marijuana to such a degree as to render me unable to fully and properly fulfill my duties and obligations as Louetta’ s father.'

Willis alleged that she told Thomas before Louetta was born that he could not smoke marijuana in the house anymore - and claimed he was 'so high' at one point that Louetta rolled off their bed while under his care in November 2023. 

She alleged that Thomas 'should not be allowed to bathe with Louetta. I feel it is highly inappropriate for [him] to bathe with Louetta naked at her age. I told him so in a text message after I heard him tell her that in November 2025.

'Since the day she was born, he has insisted on "skin on skin contact" with Louetta where he would whip off his shirt in front of anyone and have Louetta naked even when she was clearly cold so that he could have ‘skin on skin contact.’

Thomas responded in 2026 court documents that Louetta 'has never been injured in any way, has not suffered trauma or emotional or physical abuse of any kind nor been neglected at any time she’s been in my care. [Rumer] fails to detail, even a single credible instance of any mistreatment or neglect by me.'

Willis also spoke of her 'extremely ill' father, retired actor Bruce Willis , who has dementia in the documents, saying: '[Thomas] knows that many of my visits to Los Angeles since [my] move to Idaho have been to visit my father and for Louetta to spend time with her grandfather. 

'[Thomas] has made it clear to me that this is of no importance to him.

Thomas’ lawyer Michael J. Kretzmer told The Daily Mail in a statement:  'Mr. Thomas intends to try this matter in Court and not in the press. 

'We will respond to Ms. Willis' statements in court and we are confident that we will demonstrate the inaccuracy and falsity of statements alleged to have been made by Ms. Willis about the nature of their relationship, his treatment of Ms. Willis and Louetta. 

'Mr. Thomas is a caring devoted and loving father to Louetta. It is, to put it mildly, unfortunate that Ms. Willis has sought to obstruct Mr. Thomas' relationship with Louetta without justification of any kind whatsoever.'

The Daily Mail has also  contacted representatives for and for comment and has yet to hear back.
