“D and her legal posse traffic only in fiction my day in court is painfully overdue,” the statement read. “She is behaving like a coward and the truth will prevail.”

Reps for Richards and Sheen did not immediately respond to PEOPLE’s requests for comment.

Richards and Sheen first met while shooting the movieGood Advicein 2000, but it wasn’t until Richards guest-starred on Sheen’s former sitcomSpin Cityin the fall of 2001 that a romance began to blossom.

“[It was] extremely disheartening,” Richards told PEOPLE in February. “Times were extremely negative and I would have to tell myself, ‘This too shall pass.’ … I was never bitter about my divorce. Going through everything, it changed me. But I love life and I’m a glass-half-full kind of person. And I did my best to rise above.”

When Richards left Sheen, she was six months pregnant with daughter Lola.

Last season onRHOBH,Richards said that she did not take half of Sheen’s money during the divorce, despitenot having a prenuptial agreement.

“Charlie and I didn’t have a prenup when we got married and when we got divorced, I could have asked for half of what he made,” Denise said in a confessional during the season. “And I did not, because I ain’t a greedy f—— whore.”

Through the years, Richards and Sheen —who is now sober— seemingly found a way to co-parent: Richards even invited Sheen to her wedding last year toAaron Phypers.

“No matter what’s gone down with Charlie and I, I invite Charlie to anything having to do with the kids and I,” Richards said onRHOBH, which featured footage of her special day.

“Even if he did bring a prostitute as his date, I wouldn’t care,” she joked. “It’s just, it is what it is.”
