Aaron Phypers is now claiming that his estranged wife, Denise Richards, is addicted to Vicodin and is involved in an “ongoing” affair with another man, following her shocking abuse allegations against him, as previously covered by Page Six.

In a heated letter to friends and family obtained by Page Six from Phypers, he alleges that Richards requires an “intervention” for her supposed drug addiction, which has impacted their 14-year-old daughter, Eloise.

“For nearly a decade, she has battled an addiction to Vicodin (which she jokingly refers to as ‘Vitamin D’ or ‘white chestnuts’), combined with Adderall and tequila,” he asserts.

“Some of you know this has been an issue for over 20 years. She’s no longer eating real meals, and I’ve witnessed her pass out from substances — putting herself and others in danger, including while driving with our daughter.”

He also claims Richards has been involved in an affair, which he learned about earlier this year.

“She begged me not to leave, saying it was nothing and that she only loved me,” Phypers alleges in the letter.

“Then, she denied it all — even the explicit messages I found. Despite her promise to stop, more lies and shocking evidence emerged.”

Phypers further claims that she’s the one who physically abused him on July 4 — their date of separation in his divorce filing.

“On July 4th, a simple act — ordering food for our daughter Eloise — led to an unthinkable discovery. Denise accused me of using her card, and in the confusion, my phone disappeared,” he claims.

“After searching for over 20 hours and being physically attacked when I asked for it back, I eventually found it smashed inside a trash bag, hidden beneath rotting garbage and litter. When I asked why, she denied it completely. That same night, she texted me saying she was filing for divorce.”

Phypers claims he and his parents have since been “mistreated” after he filed for divorce first.

“I’ve experienced stalking (an AirTag placed on my car), been denied access to my personal belongings, and watched my elderly parents become frightened and mistreated — simply because they supported me and helped take care of Denise’s animals, her daughter, and our home,” he claims in the letter.

“This isn’t just a relationship breaking down. It’s a cry for help,” he alleges, asking for prayers for Richards.

He also doubled down on his previous denial of Richards’ allegations of abuse, claiming, “I have never, ever physically harmed my wife, and I did not give her a black eye. I have only ever stepped in to protect her or others — including separating her from physically attacking her daughter — always coming from a place of care and concern.”

Page Six has reached out to Richards for comment but did not hear back.

Richards, 54, was granted a restraining order against Phypers, 52, last Wednesday.

In court documents obtained by Page Six, she shared photos of her bruised face, claiming Phypers had abused her.

“Throughout our relationship, Aaron would frequently violently choke me, violently squeeze my head with both hands, tightly squeeze my arms, violently slap me in my face and head, aggressively slam my head into the bathroom towel rack,” Richards alleged.

She also claimed Phypers threatened to kill her and himself if she ever reported him to the cops.

She also referenced their big blowout fight on July 4, claiming he was the aggressor. Richards alleged he became “enraged” after she told him that he and his family had to move out of their marital home.

“Over the course of nearly two hours, Aaron repeatedly got within two inches of my face and screamed at me degrading profanities, including calling me a ‘c–t whore’ and a ‘piece of s–t’ and screaming at me, ‘Nobody likes you,’” she alleged in the court documents.

“Aaron repeatedly grabbed my left arm tightly in an aggressive manner. I told Aaron repeatedly that he needed to stay away from me and that he was going to hurt me.”

Phypers – who was previously caught on camera telling Richards he would “crush” her hand in a resurfaced “Real Housewives of Beverly Hills” scene – denied Richards’ allegations shortly after the filing, calling them “harmful and baseless.”

A source close to Phypers blamed the shocking picture of her black eye from her restraining order filing on her having an alleged “alcohol problem.”

“That photo was taken in winter 2022, and the fact is she was drunk at the time and fell coming up the steps to Aaron’s [since-closed medical] clinic, Q360,” the insider claimed to the Daily Mail.

Phypers filed for divorce from Richards earlier this month, listing “irreconcilable differences” as the reason for their split.
