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.
