Gladys Knight is pushing back at her son's claims that her husband, William McDowell, has inflicted "mental and financial" abuse on her. Knight, 81, assured fans she is "healthy and happy" as she continues her Queens Tour alongside Chaka Khan, Patti LaBelle and Stephanie Mills. Her statement comes after her son, Shanga Hankerson, expressed to People that he was concerned for her well-being on the tour, calling it "detrimental" to her health. He added in an interview published Friday, August 15, that McDowell urged her to take on the endeavor.
