British Olympian Tom Daley revealed to the world via YouTube that he was bisexual Monday, and now the diving bronze medalist is reported to be dating American gay screenwriter Dustin Lance Black. Both The Sun, the British tabloid, and E! Online reported about the relationship -- which has not been confirmed by either party -- where the writer is two decades older than the diver.

In the video on his own YouTube channel where Daley, 19, said he still "fancies girls," but had met "a guy," he did not name him. Queerty notes that he and Black, 39, had been seen together in Hollywood in October. Black has not publicly commented on the rumored relationship and neither has Daley, directly.

The Oscar-winning screenwriter is known for films like "Milk," "Pedro" and "J. Edgar," where the founder of the FBI, J. Edgar Hoover, played by Leonardo DiCaprio, is portrayed as having a relationship with his aide Clyde Tolson, which has been surmised by many historians.

Black won an Oscar for his screenplay for the 2008 film "Milk," and he returned to Los Angeles on Tuesday after screening the film at an LGBT festival in Russia, E! Online wrote. Daley, is across the pond in London, but took to Facebook earlier in the day to thank everyone for the positive support he’s received. "I'd just like to say a massive thanks for all the support truly was overwhelming xx."

On Monday, he explained how his life changed when he met someone special after a long-winded introduction. Toward the end of the video he said, "In spring this year, my life changed massively when I met someone and they made me feel so happy, so safe and everything just feels great."

"And that someone is a guy. It did take me by surprise a little bit. It was always in the back of my head that something like that could happen, but it wasn't until spring this year that something just clicked. It felt right and I thought, 'OK,' and my whole world changed there and then."

He added, "Of course, I still fancy girls, but right now I'm dating a guy and I couldn't be happier."
