Tom Daley is dating a 39-year-old Oscar-winner.

The 19-year-old Olympic diver admitted he was bisexual on Monday (02.12.13) and is reportedly in a seriously relationship with Dustin Lance Black, who is known for making a moving acceptance speech at the Academy Awards in 2009 when he won Best Screenplay for 'Milk', a movie about Harvey Milk, the first gay may elected to public office in California.

A friend explained: ''He's besotted with Dustin. They love each other and aren't concerned what anyone says about age difference.''

Another said: ''They are officially in a long-term relationship and talking about having a future together.

''All of their friends are completely supportive of them as a couple.

''Tom is totally besotted with Dustin -- they love each other and aren't concerned about what anyone says about their age difference.''

Tom told the world about his sexuality in a YouTube video on Monday, and Dustin is said to be ''proud'' of the hunk.

One friend told The Sun newspaper: ''Dustin is very proud of Tom for making such a powerful statement about his sexuality -- it's what he believes in doing.

''Dustin has given Tom the confidence to be himself. He's in awe of him and proud of him.

''He no longer minds people knowing they are together.''

Dustin was introduced to Tom through mutual friends at the Soho Hotel in London earlier this year and since then the Olympian has travelled to the screenwriter's Californian home for a series of secret dates.

Dustin also penned Clint Eastwood movie 'J. Edgar' but he is most famous for his Oscars speech in 2009, in which he told of how Harvey Milk had inspired him as a teenager.

He said: ''When I was 13 years old, my beautiful mother and my father moved me from a conservative Mormon home in San Antonio, Texas, to California -- and I heard the story of Harvey Milk.

''And it gave me hope. It gave me the hope to live my life. It gave me the hope one day I could live my life openly as who I am and then maybe even I could fall in love and one day get married.

''I wanna thank my mom, who has always loved me for who I am even when there was pressure not to.''
