Robin Roberts

A week after coming out on Facebook, Robin Roberts talked about her girlfriend on air for the first time.

"I have never been happier or healthier than I am right now and my year-end post was just full of gratitude and just telling everyone all that I'm grateful for, including my girlfriend Amber who really loved me through a difficult year," the Good Morning America anchor said on Monday's show.

Last month, Roberts posted a reflective year-end Facebook post revealing her relationship with Amber Laign, a massage therapist. "I am grateful for my entire family, my long time girlfriend, Amber, and friends as we prepare to celebrate a glorious new year together," shewrote. The two have been together for 10 years.

Roberts, 53, also talked on Monday's show about her holiday vacation that included her niece's wedding and shared a photo of her and Laign at the ceremony. "Next to me is my girlfriend, Amber, and my sister-in-law, Cynthia, and my brother, Butch," she said. "And it was a glorious, glorious time that weekend."
