LOS ANGELES (AP) — Robin Roberts thanked her longtime girlfriend, Amber Laign, in a year-end post published on the ABC News anchor's Facebook page on Sunday, confirmed Heather Riley of ABC. The message comes after Roberts' battle with a life-threatening illness.

The transplant — in which liquefied bone marrow donated by her sister, Sally-Ann, was slowly injected through an intravenous drip — took place in Sept., 2012 at New York's Presbyterian Hospital. At that time, it was reported that during the 90-minute procedure, "Roberts was surrounded by her closest friends, family and some co-workers."

Her 'coming out' announcement this week is the first time the "Good Morning America" anchor has publicly acknowledged her 10-year, same-sex relationship with Laign, a massage therapist from the San Francisco Bay Area.

The host reached a 100 day benchmark on Sunday following a bone marrow transplant she underwent in September 2012 to treat the blood and bone marrow disease.

In May, Grand Central Publishing announced Roberts will write a memoir telling the story of her battle with the life-threatening illness and the life lessons she continues to gather following her return to "GMA" this past February.
