Celebrating her one year anniversary of reaching the "critical milestone" of 100 days post-bone marrow transplant, GMA host Robin Roberts took to Facebook today to reflect on her journey and for the first time publicly acknowledged her longtime girlfriend, Amber Laign. Mediabistro reports:

Roberts has been out to her family, friends and co-workers for years, but this is the first time she’s publicly acknowledged her sexuality.

"I am grateful for my entire family, my long time girlfriend, Amber, and friends as we prepare to celebrate a glorious new year together."

Roberts and Laign have been together for 10 years. Laign, a massage therapist who works with patients recovering from injuries, is originally from the San Francisco Bay Area.

A year ago today, Roberts reached the 100 day mark following her bone marrow transplant. Her posting today is a message of thanks for all who helped her along the way.
