The 53-year-old Roberts opens up to the magazine about the challenges she faced after being diagnosed with the disease myelodysplastic syndrome.
"A doctor told me I had one to two years to live without a transplant," she said, explaining that she's now also speaking about the people who loved her through the ordeal, including her girlfriend of nine years, Amber Laign. "How could I not?" says Roberts about acknowledging 39-year-old Laign's role as her caregiver.
"Even though Amber is someone who shies away from the spotlight, it was important for me to let people know I have this person in my life," Roberts revealed. She also revealed she still receives low-intensity chemotherapy shots every six to eight weeks and will continue to do so until the second anniversary of her bone marrow transplant later this year.
