Martha Stewart’s ex-husband Andrew “Andy” Stewart and his wife Shyla Nelson Stewart broke their silence on claims made by the lifestyle mogul in the new documentary “Martha.”In the Netflix film, Martha, 83, accused Andrew of having numerous affairs during their 29-year marriage and also revealed that she had been unfaithful to him. “Young women, listen to my advice, if you’re married and your husband starts to cheat on you, he’s a piece of s—,” Martha, who was married to Andrew from 1961 to 1990, said in the documentary’s trailer. “Get out of that marriage.” Andrew and Shyla shared their response in a statement that was signed by both of them and posted on Facebook ahead of the documentary’s Oct. 30 release. “Hello FB family – this is my first and will be my only public comment on this subject. Since I am not active on any other social media platform, this is the only place I am sharing this,” Shyla wrote in the post she uploaded on her page.MARTHA STEWART DOCUMENTARY: TOP 5 BOMBSHELLS, FROM ‘BIGOT’ FATHER’S SLAP TO AFFAIR WITH ‘ATTRACTIVE IRISHMAN’She continued, “As some of you know, my husband is Andrew Stewart – brilliant publisher, avocational naturalist and nature photographer, and one of the gentlest, most soft-spoken, kind-hearted men I’ve ever known.””No one was more surprised than we when, after being introduced as colleagues almost 12 years ago, our connection blossomed into a deep and everlasting love,” Shyla added. “With our shared devotion to the Earth and to our families at the center, Andy and I have built a life of beauty, meaning, productivity, and purpose, infused with true love, which we share as fully as we can with our beautiful blended family of 5 amazing adult children, our 3 adorable grandchildren, our extended family, and many cherished friends.”She went on to address Andrew’s past, writing that her husband had experienced difficult times before they fell in love.”Prior to this happy chapter of his life, Andy had some dark ones, including a painful and abusive marriage to Martha (as in, Martha Stewart), which ended almost 40 years ago,” Shyla claimed. She continued, “While Andy quietly moved on and forward with his life, it appears that Martha continues to publicly relitigate the marriage, including comments in a sensationalized trailer for an upcoming documentary on Netflix.” “The juxtaposition of Andy’s early life with the joy-filled, purpose-led, loving marriage we live today is striking,” Shyla added. “Every day, we openly express our gratitude for our love and for our life together.”We both wish everyone, including Martha herself, the experience of loving and being loved deeply and fully, and the peace that comes from such a love,” she concluded in the post, which featured photos of herself and Andrew.LIKE WHAT YOU’RE READING?
