British Olympic diver Tom Daley says his family supports his decision to come out.

Daley announced in a YouTube clip he posted that he's in love with another man.

The 19-year-old Daley is widely believed to be dating Milk screenwriter and LGBT rights activist Dustin Lance Black.

In an interview with the UK's Jonathan Ross broadcast Saturday, Daley described how he met his boyfriend.

“I'd never felt like anything like it before,” Daley said. “We were at a party and I hadn't even spoken to him all night. I didn't know what to do or if he was gay at first. I typed 'call me' in his notes with a smiley face on his phone, and the next day he texted. He makes me feel safe and happy, right now I couldn't be happier.”

“I'd never felt the feeling of love, it happened so quickly. I was completely overwhelmed by it to the point I can't get him out of my head all the time. I've never had it before where I love someone and they love me just as much.”

“My family … they're all so supportive of me and I couldn't ask for anything more,” Daley added. (The video is embedded on this page. Visit our video library for more videos.)
