He wrote: “Whats going on gang?I'm doing great! Stronger than ever! I'm here relaxing @ home enjoying ur messages! I feel the love! Thanx for all! peace.”
The Puerto Rican star also wrote the message in Spanish for his international fan base.
Writing on his official website, Ricky claimed it was the birth of his twin boys Matteo and Valentino from a surrogate in August 2008 that led him to admit his sexuality.
He said: “To keep living as I did up until today would be to indirectly diminish the glow that my kids where born with. Enough is enough. This has to change.”
The "Livin’ la Vida Loca" singer also revealed it took him many years of contemplation to announce he was a homosexual man.
He said: “This was not supposed to happen 5 or 10 years ago, it is supposed to happen now. Today is my day, this is my time, and this is my moment.
“These years in silence and reflection made me stronger and reminded me that acceptance has to come from within and that this kind of truth gives me the power to conquer emotions I didn't even know existed.
“I am proud to say that I am a fortunate homosexual man. I am very blessed to be who I am.”
