British tab The Sun and E! News are both reporting that the guy dating British diver Tom Daley is none other than Milk screenwriter Dustin Lance Black.
Said Daley in his video: "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."
