The Facebook message marks the first time that Roberts has publicly mentioned her girlfriend, though the morning show host has often been open about her health battles.
Roberts also posted a photo of herself one year ago, reuniting with her dog 100 days after her 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.
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.
Wishing you a Healthy and Happy New Year.
Peace, love, and blessings to all..XO
