LOS ANGELES, CALIFORNIA: Chrissie Carnell Bixler, one of the accusers of actor Danny Masterson, has taken to Instagram Stories to express her outrage over the support lent by fellow 'That '70s Show' co-stars Ashton Kutcher and Mila Kunis in a character reference letter for Masterson, who recently received a 30-year to life jail sentence for rape.

Bixler's accusations have thrown a shadow of doubt over the couple's support, hinting at undisclosed secrets and suggesting that they may have knowledge of troubling incidents related to Masterson.

Chrissie Bixler drops bombshell on Ashton Kutcher

Bixler posted an image from a report that quoted Kutcher and Kunis describing Masterson as a "role model" with "exceptional character."

She boldly claimed, "Dear Ashton, I know the secrets your 'role model' keeps for you. Ones that would end you. Did you forget I was there? You were on speaker phone that night you called Danny on February 21, 2001. I heard everything. I heard the plan. In my opinion, you're just as sick as your 'mentor.'"

The shocking allegations have left many wondering about the nature of these undisclosed secrets and what exactly transpired during that phone call.

What happened to Ashley Ellerin?

Bixler appeared to be referring to a particular night in February 2001 when Ashton Kutcher had attempted to pick up his date, Ashley Ellerin, but she reportedly never answered the door.

The next day, it emerged that she had been brutally murdered by the "Hollywood Ripper," Michael Gargiulo. Ellerin had suffered 47 stab wounds, 12 of which were considered individually fatal.

Kutcher had been deeply affected by the incident and even contacted the police, expressing concerns about his fingerprints being on her doorknob.

“My fingerprints are on this door and I was freaking out,” he stated. “I told [an officer], ‘Let me tell you what happened.’ ”

Bixler's mention of this night in relation to the secrets she claims to know has intensified the mystery surrounding her allegations.

Chrissie Bixler addresses Mila Kunis

Turning her attention to Mila Kunis, Bixler hinted at an alleged troubling situation involving Kunis and Masterson. She urged Kunis to reflect on her experiences as a child on the 'That '70s Show' set, suggesting that her old interviews contain revealing information.

“Dear Mila, I pray you begin to process what you experienced as a child on that set. Your old interviews are very telling (I encourage everyone to watch them and decide for yourself what you hear and see. Do so before they get scrubbed from the internet)" she wrote.

"I also know what happened in Toronto and after. Question, if that’s what you view as a normal relationship with a ‘big brother figure’ then I feel very sad for you, and I hope you consider getting into therapy. You all must forget I was there the whole time those first 5 years of That 70’s Show. I remember everything," she added.

Bixler's cryptic statements imply that there may be undisclosed incidents involving Kunis and Masterson that the public is unaware of.

Kutcher and Kunis were not the only 'That '70s Show' alumni to write letters of support for Masterson. Debra Jo Rupp and Kurtwood Smith, who played Kitty and Red Foreman on the show, also participated. However, conspicuously absent from this list was Topher Grace, who portrayed Eric Foreman.

Was Topher Grace bullied by Danny Masterson?

Bixler alleged that Masterson had "bullied" Grace on set. “Topher was bullied by Danny Masterson and isolated by most of them because Danny’s like a cult leader. Danny hated Topher because Topher didn’t bow to Danny like his other younger castmates," she wrote.

"I loved Topher. If I so much as said hi to Topher, I would be given a scolding and then ignored by Danny. It broke my heart. He was the only guy on that set with integrity and a moral compass. That’s my experience. I was there," she added.

Grace's wife, Ashley Hinshaw, expressed support for sexual assault victims following Masterson's sentencing. "To every rape victim that is [re-traumatized] by witnessing society debate and focus their attention on what is going to happen to the RAPIST...I see you," she wrote on Instagram Stories over a photo of trees on a sunny day.

As of now, neither Mila Kunis nor Ashton Kutcher has responded to Bixler's allegations. However, they have publicly apologized for "the pain that has been caused by the character letters that we wrote on behalf of Danny Masterson.”

At this point, it is important to note that Chrissie Bixler's allegations are just that. Regardless, they have cast a shadow over the support offered by Kutcher and Kunis and have raised many questions about undisclosed secrets and troubling incidents surrounding the 'That '70s Show' cast.
