Sarah Silverman revealed a shocking family secret that her late father, Donald Silverman, once shared with her about her baby brother Jeffrey's tragic death.In a new interview with Rolling Stone, the 54-year-old comedian recalled the moment that Donald told her about how he believed Jeffrey, who passed away at three-months-old, really died."Im going to tell you a big bomb," Silverman said.Silverman recalled that for most of her life, she was always told one version of the circumstances behind Jeffrey's death. The "Saturday Night Live" alum explained that at the time of Jeffrey's death, her paternal grandparents, Max and Rose, were caring for the infant while Donald and her late mother Beth Ann O'Hara were on vacation."The story was that something happened with the crib, and Jeffreys little body slid and he got suffocated," Silverman said. "But if you look back, there was never a lawsuit with the crib company or anything."However, Silverman told the outlet that Donald shared a very different story in 2022 when he attended a production of her musical "The Bedwetter" at the Atlantic Theatre Company's Linda Gross Theatre in New York City. "The Bedwetter" is an adaptation of Silverman's 2010 memoir of the same name.The show included a scene in which a younger version of Silverman made a joke about Jeffrey's death. Silverman recalled that Donald visited her afterward and made a shocking revelation about how he believed his allegedly "violent" late father Max was involved in Jeffrey's passing.SARAH SILVERMAN SLAMS JOY REID AS MEDIA PANICS ABOUT DESANTIS' PROPOSED CIVILIAN MILITARY FORCE IN FLORIDA"My dad says, I always felt that he was crying or something, and my dad shook him," Silverman told Rolling Stone. "He shook him in a rage and killed him."Silverman said that Donald's story immediately made sense to her because her father had endured a "heartbreaking childhood," during which "his dad beat the s--- out of him every day, just mercilessly."LIKE WHAT YOURE READING?
