Rumer Willis’ ex Derek Thomas is now claiming that Demi Moore threatened to “ruin” him as his ongoing custody battle over his and Rumer’s daughter Louetta worsens.
In a recent court filing, Thomas told the judge that Loomer “directly informed him that he did not want his family to be present for the first 40 days following the birth of Louetta in 2023,” Thomas told the US Sun in a recent court filing.
“Nevertheless, the day after Louetta was born, Ms. Moore and her domestic staff came to the house and caused a huge disturbance.”
“At that time, Mr. Moore apparently threatened to ‘ruin me’ based on (Mr. Loomer’s) statements.”
Representatives for Willis and Moore did not immediately respond to Page Six’s requests for comment.
As previously reported, Thomas hit back at Willis’ domestic violence claims in court earlier this week, telling the court in a June 2 filing that he never acted “aggressively or inappropriately” toward Willis.
The lawsuit also accused Willis of inappropriate behavior toward his daughter by featuring her in sponsored “adult sexual humor” content without her permission.
Thomas insisted he was an active father and FaceTimed his daughter every day, despite Willis, 37, allegedly banning him from seeing her. He also denied allegations of drug use and unpaid child support, telling the court he was willing to pay the $2,350 per month.
She also discussed how the Now and Then star first moved to Idaho with her daughter to escape the toxic air quality during the 2025 Los Angeles wildfires.
However, she is said to have subsequently attempted to permanently reside in Kitanakashu. In response, he said he “never agreed with (Rumer) to move out of state,” and that he never agreed to move permanently with her after Louetta’s birth.
However, Willis reportedly told Thomas on several occasions that she wanted to move to Texas or another state to be free from her mother’s domineering and hostile behavior.
Willis filed legal documents last month accusing her ex-husband of “constant domestic violence” after he requested custody and visitation rights for their child in July 2025.
She claimed Thomas had a “persistent pattern” of “erratic emotional abuse” and displayed it in front of Louetta before they broke up in August 2024.
“He engaged in continuous coercive control through long-term, cyclical verbal attacks that he was unable or unwilling to stop. (He) continued to engage in these types of attacks for more than six hours at a time, which became daily,” court documents state.
“I always tried to keep the peace and walk on eggshells,” she claimed. “He wanted to isolate me from my friends and family. He kept calling me a liar for no reason. He always told me I was a bad girlfriend.”
Rumer continued. “He was acting paranoid that my mother and I were trying to separate him. When Louetta was a newborn, he got very angry with me because I wouldn’t let his mother smoke pot in the house.”
At the time, Moore corroborated her daughter’s claims, adding that Thomas acted with “no regard for Ruemer, the baby, the process or anyone else” and became aggressive when Louetta was born.
Thomas initially condemned Willis’ claims of domestic violence in a statement, saying, “I did not engage in any form of domestic violence, including active coercive control. (Our) relationship was unhealthy and ended appropriately, but there was no violence, physical or emotional attack, or intimidation on my part.”
His lawyer also denied the allegations, calling them “substantially inaccurate.”
