The model and actress passed away last month at the age of 51. As established in a death certificate obtained by TMZ, Keisha's death was caused by "alcoholic liver disease" - a condition she had been living with for years. The document also lists acute renal failure as another contributing factor. According to the certificate, Keisha was laid to rest in Los Angeles on 20 December, two weeks after she passed. Forest and Keisha were married for over 20 years and had two children together, Sonnet, 27, and True, 25. "Goodbye mommy," True wrote on her Instagram Stories following Keisha's passing.
