“Good Morning America” co-anchor Robin Roberts has acknowledged publicly for the first time a longstanding relationship with a woman, marking another bout of personal disclosure for the popular newswoman whose 2012 fight with myleodysplastic syndrome corresponded with a surge in the ratings for the ABC morning show. In a post made Sunday on Facebook, Roberts said she was mulling her state a year earlier, in 2012, when she reached an important 100 day-milestone after undergoing a blood marrow transplant.

“At this moment I am at peace and filled with joy and gratitude. I am grateful to God, my doctors and nurses for my restored good health,” she wrote. “I am grateful for my sister, Sally-Ann, for being my donor and giving me the gift of life. I am grateful for my entire family, my long time girlfriend, Amber, and friends as we prepare to celebrate a glorious new year together. I am grateful for the many prayers and well wishes for my recovery. I return every one of them to you 100 fold. On this last Sunday of 2013 I encourage you to reflect on what you are grateful for too.”

An ABC News spokeswoman said Roberts has been in a ten-year relationship with a woman named Amber Laign, a massage therapist in private practice originally from the Bay Area, and noted that the two had met through mutual friends. Laign specializes in helping people recovering from injuries, the spokeswoman said.
