Olympic diver Tom Daley has admitted that he fell in love "quickly" when he met his new partner, who is rumoured to be Oscar-winning director Dustin Lance Black.

The 19-year-old sportsman revealed in a YouTube video on Monday that he is in a relationship with a man.

While appearing on The Jonathan Ross Show, Daley revealed that he met his current love at a party earlier this year and that he made the first move by telling him to get in touch.

"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," Daley said on the show. "I've never had it before where I love someone and they love me just as much."

Daley's appearance on the show will be aired on ITV on December 7.
