LONDON: British Olympic diver Tom Daley and Oscar-winning screenwriter Dustin Lance Black have announced their engagement. The announcement was published in The Times newspaper Thursday, but did not disclose a date for the marriage. Black is a writer and producer who won an Academy Award for his screenplay for the 2008 movie 'Milk' about gay activist and politician Harvey Milk. Daley won a bronze medal at the 2012 Olympics in London and his youthful exuberance made him a fan favorite. He came out as a gay man in a YouTube video nearly two years ago, announcing that he was dating a man and couldn't be happier.
