The past month will likely go down as one of the worst in Brooke Mueller’s life. Shortly after husband Charlie Sheen reportedly threatened her with a knife on Christmas, the new mom was hospitalized with a life-threatening illness. As she struggles to get healthy again, she’s been plagued by vicious gossip about drug and alcohol abuse. “There are so many lies out there,” Brooke tells In Touch exclusively, and those close to her want to set the record straight. When Brooke, 32, was rushed to the hospital on January 20, it was because of a dangerous fever resulting from having her wisdom teeth removed — surgery she delayed because of the stress over Charlie’s court date. It was not, as some speculated, because she had been drinking too much. “The infections and pneumonia are what caused the shutting down of her organs,” her mother, Moira Fiore, tells In Touch. “Brooke was very sick.” But when Brooke checked herself into the Two Dreams facility in North Carolina after her release on January 26, the rumors quickly multiplied and grew wilder because of her problems with Charlie. She was said to have relapsed into a crack and alcohol problem and was even accused of having drugs brought to her in the ICU. It’s all nonsense, according to her inner circle. “This is ridiculous!” says her outraged mom. “There were tubes down her throat — how in the world would anyone in this position do drugs?” And since her 11-month-old sons, Bob and Max, mean the world to her, another rumor — that she had to go to rehab for drinking during her pregnancy — was especially hurtful. “It’s so horrible to say,” Moira adds. “She would never put her boys at risk.”
