"I want to take this moment to thank our friends and family for all of the love and prayers," she wrote. "It is with a very heavy heart that I inform everyone that my sister, Denise Dowse, has gone forward to meet our family in eternal life."
She continued, "Denise Yvonne Dowse was the most amazing sister, a consummate, illustrious actress, mentor and director. She was my very best friend and final family member. Denise loved all of you. I know that she is watching over us with all the love she has."

He continued, "Some of my heartiest off camera laughs were between she and I hammering out the the discipline her Mrs. Teasley would dish out to my Steve Sanders. My sincere condolences to her family, and all others who she was dear to."
Tracey shared earlier this month that her sister was ill.
