He has been guarded about his sexuality for years and reserved about his decision to become a father, but Martin will tell all to Winfrey, reported Daily Mail online.
Martin welcomed cameras to his home for a candid portrait of his home life for the interview with Oprah, in which he talks about his sons and his sexuality for the first time.
The 39-year-old Puerto Rican megastar quietly became father of twin boys, called Matteo and Valentino, in August 2008.
Previously, the star has only released occasional pictures of himself with the two gorgeous children via his official Twitter account.
The 'Livin Da Vida Loca' hitmaker had come out earlier this year with a announcement on his website.
"I am proud to say that I am a fortunate homosexual man. I am very blessed to be who I am," the singer had said at the time.
Before he came out as gay, the star had a 14-year on-off relationship with Mexican TV host Rebecca de Alba. However, they split for good in 2005.
