In a Facebook message posted this weekend, Robin Roberts spoke about her sexuality for the first time, thanking her long-time girlfriend Amber for her incredible support this year.

"I am grateful for my entire family, my long time girlfriend, Amber, and friends as we prepare to celebrate a glorious new year together," the "Good Morning America" anchor wrote.

The post, which coincided with the 100th day of her recovery from her bone marrow transplant, is poignant for Roberts who has never addressed her sexual orientation publicly.

Scroll down to see which other celebrities came out in 2013:

Jodie Foster

While accepting her Cecil B. DeMille award at the Oscars this year, Foster addressed her sexuality by saying,

"I already did my coming out a thousand years ago, in the Stone Age. Those very quaint days when a fragile young girl would open up to friends and family and co-workers then gradually to everyone that knew her, everyone she actually met.

"But now apparently I'm told that every celebrity is to honor the details of their private life with a press conference, a fragrance and a primetime reality show."

She also thanked her former partner Cydney Bernard, saying:

"There's no way I could ever stand here without acknowledging one of the deepest loves of my life: my heroic co-parent, my ex-partner in love but righteous soul sister in life, my confessor, ski buddy, consigliere, most beloved BFF of 20 years, Cydney Bernard."

Bob Harper

Actor Wentworth Miller, known for his role in the TV series "Prison Break," discussed his sexuality in an open letter penned to St. Petersburg International Film Festival director Maria Averbakh.

Miller declined an invitation to attend the festival citing Russia's strict anti-gay laws.

He wrote: "As someone who has enjoyed visiting Russia in the past and can also claim a degree of Russian ancestry, it would make me happy to say yes. However, as a gay man, I must decline.

"I am deeply troubled by the current attitude toward and treatment of gay men and women by the Russian government," he added.
