ABC News corespondent and Good Morning America cohost Robin Roberts has publicly acknowledged her sexuality for the first time ever in an end-of-year Facebook post. 

"At this moment I am at peace and filled with joy and gratitude," Roberts wrote on Facebook Sunday afternoon, explaining how grateful she is after her rough year.

But buried in the note for the eagle-eyed is the first time Roberts has ever publicly acknowledged her long-term relationship with Amber Laign. "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 said. TVNewser says the two have been together for ten years. 

Roberts' sexuality has been something of an open secret — it was never hidden from her friends, family and colleagues, but Roberts never mentioned it during her long career at ESPN or at ABC, or in interviews about her private life. When the President wanted to officially announce his support for gay marriage, it was Robin Roberts who scored the sit-down interview.  

Roberts has had an impossibly rough year, but things are starting to turn around. After taking 174 days off work to receive a blood marrow transplant and fight a rare blood disorder, Roberts returned to work earlier this year and seems as healthy and happy as ever.
