Rumer Willis’ bitter custody fight with ex Derek Richard Thomas has already exposed painful details about their fractured relationship, but the situation escalated even further once Demi Moore stepped into the legal battle herself. 

The actress shocked many after filing court documents supporting her daughter and describing troubling incidents surrounding the birth of little Louetta. 

Now, insiders are revealing how deeply Moore has become invested in protecting both her daughter and granddaughter as the family’s emotional court war continues unfolding behind the scenes.

Rumer Willis’ Custody Battle Draws Demi Moore Into The Spotlight

Rumer Willis and Derek Richard Thomas have been locked in a contentious custody dispute over their three-year-old daughter, Louetta, for nearly a year. 

While the legal fight had already become heated, Moore’s recent court filing has intensified public attention after she accused Thomas of displaying “aggressive” behavior during Louetta’s home birth.

According to an insider who spoke with the Daily Mail, Moore has become increasingly uncomfortable around Thomas and has no desire to build any relationship with him moving forward. 

The source explained that the 63-year-old’s primary concern remains supporting her daughter and granddaughter while keeping family matters as stable as possible.

“Demi is comfortable with people knowing how she feels about Derek, because she is uncomfortable with him and the less he is around, the better,” the insider said.

The source added that Moore wants everything centered around family rather than ongoing conflict. “Her main focus has always been supporting her daughter Rumer and her granddaughter Louetta, and she stands firmly by them,” the insider shared.

Rumer’s family Bond Stands In Contrast To Derek Thomas Drama

The insider also pointed to the close relationship Moore still shares with ex-husband Bruce Willis despite their divorce over two decades ago. 

Moore and Bruce have remained united while navigating the actor’s devastating dementia diagnosis alongside his wife Emma Heming and their blended family.

The source suggested that the “Margin Call” actress’s successful co-parenting experience with Bruce has heavily influenced how she views Thomas.

“It’s clear that Demi knows when a relationship works or not being with Bruce,” the source said before adding, “But to compare Bruce and Derek is like comparing a million dollars to a clogged toilet.”

Another insider explained that Rumer Willis remains extremely close with her mother and relies heavily on her family for support while raising Louetta. 

Moore reportedly helps care for the child whenever possible, while sisters Scout and Tallulah also remain actively involved.

“Demi helps with the baby whenever she can,” the source said. “Her family is very close and her sisters are also helpful.”

The insider added that Rumer’s life has become completely centered around her daughter as she attempts to navigate the complicated legal situation.

Rumer Willis Alleged Thomas Created Stress During Pregnancy And Birth

Court filings submitted by Moore painted a disturbing picture of the former couple’s relationship before and after Louetta’s birth. 

The actress claimed she witnessed her daughter in “a constant state of stress” throughout the pregnancy and alleged that Thomas frequently prioritized himself over Rumer.

Moore described one alarming moment during the home birth, claiming the musician suddenly entered the birthing tub without warning while Rumer was in labor.

“Everyone was shocked,” Moore alleged in the filing, adding that Rumer immediately told him to leave the tub.

According to the producer, Thomas then spent the remainder of the labor “acting angry and pouting, and making it all about him.” 

She further alleged that he later became upset when Moore and Scout returned to help clean the home after the birth.

According to her, Thomas angrily complained about their presence and pressured Rumer to distance herself from family support. 

More also alleged that her grandchild’s father demanded “skin to skin contact” with Louetta immediately after birth while the baby was cold and needed to be bundled.

The actress further claimed Thomas attempted to isolate Rumer from her support system and made little effort to contribute financially or physically to parenting responsibilities.

Rumer Claimed She Felt Afraid During Relationship

Rumer Willis’ own court filings contained additional allegations about the relationship’s breakdown. She accused her ex-boyfriend of engaging in “incessant domestic violence in the form of coercive control,” claims he has denied.

The 37-year-old alleged she became fearful shortly after Louetta’s birth as Thomas’ behavior allegedly became increasingly “erratic and bizarre.”

“I was in a fragile postpartum state, and he was causing me a lot of stress,” Rumer wrote. “I also became afraid for myself and our baby, so I was constantly trying to keep the peace and walk on eggshells.”

She further accused Thomas of attempting to isolate her from loved ones while repeatedly criticizing her. According to the mom of one, Thomas became paranoid and believed she and Moore were trying to take Louetta away from him.

The actress additionally claimed the singer refused to contribute financially toward their daughter’s expenses despite expecting her and her “wealthy family” to handle everything. 

Court documents stated Rumer earns income through her production company and rental property while paying between $15,000 and $21,000 monthly for childcare, groceries, and other expenses.

Rumer Willis’ Ex Strongly Denies All Abuse Allegations

Thomas has firmly denied all accusations made against him in court documents filed earlier this year. He acknowledged that the relationship with Rumer was unhealthy but insisted there was never any abuse or coercive control involved.

“I have committed no acts of domestic violence in any form, including any active ‘coercive control,’” Thomas stated in his filing.

He also disputed claims regarding neglect or mistreatment of Louetta and insisted their daughter had “never been injured in any way” while in his care. 

He claimed he only used marijuana legally and denied it ever interfered with his parenting responsibilities. Through attorney Michael J. Kretzmer, Thomas also criticized Rumer for attempting to litigate the case publicly rather than strictly through the courts.

“Mr. Thomas intends to try this matter in Court and not in the press,” the lawyer told the Daily Mail. The attorney added that Thomas is “a caring devoted and loving father to Louetta” and claimed Rumer has attempted to obstruct his relationship with their daughter “without justification of any kind whatsoever.”

Despite the escalating accusations on both sides, insiders say Moore remains focused on one thing above all else, which is “the priority is Louetta’s wellbeing and making sure she’s protected and surrounded by stability.”
