R&B sensation Frank Ocean broke into tears after "coming out" as a gay man because he was so happy to finally open up about his sexuality.

The star shocked fans when he posted a blog on his Tumblr.com account in July (12) and Ocean admits he was so overwhelmed with relief he started crying the moment he revealed the news to his followers.

He tells GQ magazine, "The night I posted it, I cried like a f**king baby. It was like all the frequency just clicked to a change in my head. All the receptors were now receiving a different signal, and I was happy. I hadn't been happy in so long. I've been sad again since, but it's a totally different take on sad. There's just some magic in truth and honesty and openness."

And the singer insists he was stunned to receive such love and support from fellow artists like Beyonce and Russell Simmons - because he worried his confession might end his career.

He adds, "I had those fears. In black music, we've got so many leaps and bounds to make with acceptance and tolerance in regard to that issue. It reflects something just ingrained."
