Tom Daley to marry Oscar-winning film-maker Dustin Lance Black

Two years after he posted an impassioned message about his sexuality on YouTube, Tom Daley is preparing to marry Oscar-winning screenwriter Dustin Lance Black. The Olympic diver, who qualified in August for the 2016 Rio Olympics, snubbed social media to announce his engagement in the births, marriages and deaths column of The Times newspaper.

The notice reads: "The engagement is announced between Tom, son of Robert and Debra Daley of Plymouth, and Lance, son of Jeff Bisch of Philadelphia and Anne Bisch of Lake Providence."

Daley, 21, started dating Black in 2013, five years after the American won an Academy Award for best original screenplay for the film Milk. The couple went public with their romance weeks after the British athlete revealed he was gay in a YouTube video because he "wanted to say what I wanted to say without anyone twisting it".

"It really was love at first sight," Daley later told ITV's Jonathan Ross. "I'd never felt anything like it before. We were at a party and I hadn't even spoken to him all night. I didn't know what to do or if he was gay at first. I made the first move, I typed 'call me' in his notes with a smiley face on this phone and the next day he texted."

Back in March, the couple marked their second anniversary by sharing sweet messages on Instagram. Daley shared the first selfie he took with Black on the social networking site and also revealed his pet name for Black. "2 years ago I met my [frog] and my life changed forever! Thank you for making these past 2 years so special," the caption read.

Black, 41, returned the sentiment by writing a heartfelt message on his own Facebook page: "Two years ago we took a selfie just after meeting... the very moment my life changed forever. Happy Anniversary my love."
