Tom Daley admits he is bisexual.

The 19-year-old diver is enjoying a relationship with a man and although at first his feelings took him by ''surprise'' he feels ''happy'' and ''safe'' in his current romance.

Speaking in a YouTube video posted on his official page, he explained: ''In spring this year my life changed massively when I met someone, and they make me feel so happy, so safe and everything just feels great. 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.

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

Tom - who presents celebrity diving TV show 'Splash!' - is hoping fans support his decision to come out and back him as he trains for the next Olympics in Rio de Janeiro, Brazil, in 2016.

He said: ''My friends and family have supported me and I hope you guys can too.

''I still want to win an Olympic gold medal in Rio in 2016 for Britain.

''I'm still as motivated as ever to do that.''
