Tom Daley, Dustin Lance Black Celebrate With Beef Wellington

British Olympic diver Tom Daley has shared the first photo of himself and Hollywood screenwriter Dustin Lance Black.

Daley, 19, announced last month in a YouTube clip that he's in love with another man. Though he did not reveal the man's name, he is widely believed to be Black, 39, who is also a prominent LGBT rights activist.

“#Splash celebrations :) Beef Wellington...yes please!!!” Daley captioned a photo of the pair on Instagram.

Splash is the UK reality series that follows celebrities as they try to master the art of diving. Daley returned for the show's second season, which premiered on Saturday.

In an interview with the UK's Jonathan Ross, Daley explained that it was “love at first sight” for him.

“I'd never felt like anything like it before,” Daley said. “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 typed 'call me' in his notes with a smiley face on his phone, and the next day he texted. He makes me feel safe and happy, right now I couldn't be happier.”
