Roberts’ sexuality had been known to her family, friends and co-workers, according to The Wrap, adding that the mention of longtime girlfriend Amber Laign was her first public acknowledgement.

“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 posted as part of a thank-you message for those who had supported her after her bone marrow transplant last year.

Roberts was diagnosed with myelodysplastic syndrome (MDS) and took a leave from “GMA” to undergo the transplant in October of 2012. She returned to the show in February 20, 2013, The Wrap noted.

TheBlaze reported that Roberts was specifically chosen by the White House for the famous interview in May 2012 in which President Obama announced his support of gay marriage.

Michelle Obama used her Twitter account to show support for Roberts after she announced her blood disorder:

@RobinRoberts, Barack and I have you in our prayers. We believe in you and thank you for bringing awareness and hope to others. –mo
