Olympian Tom Daley is 20 years younger than his screenwriter husband, Dustin Lance Black. Here's a timeline of their relationship.

Daley was in Los Angeles after winning a Nickelodeon Kids' Choice Award, so his friend organized a dinner to celebrate. Black reluctantly showed up to the dinner in a red hoodie and caught Daley looking at him several times throughout the meal, even though the diver didn't know who Black, a Hollywood screenwriter, was.

When Black was about to leave, Daley put his phone number in his phone and they met up the following night at a hotel bar. They talked for hours, confessing they wanted to get married and have children.

"Love is a commitment to me — something that goes deep," Black told Out magazine in 2016. "You can't have that at first sight. It has to be earned. But did we start to fall in love at first sight? I believe so."

In May 2013, Daley turned 19 years old, and Black was 38. The pair celebrated by going to a party, and the following day, they had their first official date.

"That was the night he said, 'Tom will you be my boyfriend?' when we were drunk in the hotel, and then he said, 'Actually, you don't have to answer that,'" Daley told Out magazine in 2016. "When I woke up the next morning, I turned to him and said, 'Yes.' And he said, 'What do you mean, 'Yes'?' And I said, 'Yes, I'll be your boyfriend.'"

"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," the Olympic diver said in the video. "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."

He went on to say, "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."

In the interview, Daley didn't name his new boyfriend but said that he couldn't "get him out of my head."

"I never had it before where I love someone as much as they love me," he said. "I've never felt so happy and in love."

For a few weeks, the two kept trying to propose to each other, but the moment or situation never felt right. Finally, as they were getting ready for bed one night in England, Daley got down on one knee and popped the question. Black ran to the bathroom and got the ring he planned on proposing with and gave a speech.

"From the Golden Gate Bridge to the Tower Bridge without success, and finally it happened in our underwear," Black told Out magazine in 2016.

Daley posted a picture on Instagram of the two rings on top of a newspaper announcing their engagement. The diver captioned the photo "and then #ISaidYes."

When Smith won an Academy Award in 2016 for his "James Bond" song, they said they were the first openly gay man to win an Oscar. In fact, Black had won a best original screenplay Oscar for writing "Milk" in 2009.

Black took to Twitter to complain, writing, "Hey @SamSmithWorld, if you have no idea who I am, it may be time to stop texting my fiancé. Here's a start." He linked to his Oscar acceptance speech.

The tweet went viral and the beef continued until 2019 when Black apologized to the singer on stage at their concert.

"Sam, I am so sorry," he said at the time. "Sometimes I get carried away, and you are a motherf------ blessing of a human being, so thank you."

When nude images and a video of Daley leaked online, he admitted he had sent them to a fan during a secret seven-month break from Black in 2016. The couple had taken a break after struggling to keep their relationship intact while living long distance.

Daley said he told Black about the nude photos when they got back together.

"Me and Lance after working through that distance through the amount of time we've been together, sometimes it takes something like a little bit of time apart to realise how fond you are of each other," he told The Sun.

Lance also confirmed they worked through the nude photo incident.

"Tom and I talked about anything and everything that went on. That's the secret to how we are so close and can survive tough times," he said. "What Tom did in that time was his personal business."

Daley went on to say, "This will absolutely never happen again now that we're getting married. The date is set, and we're raring and ready to go for that wedding now."

The pair held their wedding ceremony at Bovey Castle Hotel on Dartmoor, Devon, which is about 30 miles from Daley's hometown of Plymouth.

"On 6th May 2017, I married the love of my life, @dlanceblack," Daley wrote on Instagram at the time. "We shared the day with 120 of our closest friends and family, from Texarkana to Plymouth! Thank you to everyone who made this weekend the most special weekend of our lives!"

"I don't really think about age, and we never notice the age gap," Daley told the Belfast Telegraph. "Funnily enough, I feel older in terms of maturity. I had to grow up quickly because I was only 10 when I first traveled to Australia without my parents to compete."

"Happy Valentine's Day," Daley wrote on Instagram with a picture of him and Black holding up an ultrasound photo of their baby.

"Welcome to the world our precious little Robbie Ray Black-Daley," Daley wrote on Twitter at the time. "The amount of love and joy you have brought into our life is immeasurable, our precious little son."

"There is so much that you aren't prepared to feel when you become a parent. I never knew I could love anything as much as I love my son," Daley told the magazine. "He is the best thing to ever happen to us."

He went on to describe his relationship with Black now that they're fathers.

"We have been on a couple of date nights since Robbie was born but quite honestly, spending time together as a family is so special for us, we are just loving every minute," he said. "We split the changing and nighttime wake-ups. I think we make a great team!"

The Olympian added, "I'm definitely the strict one out of the two of us. I like to get Robbie into a routine, and Lance looks at his cute face and always caves."

"I got to spend so much bonding time with my family," Daley told RadioTimes. "Before getting married and having a kid, I used to define myself by how well I do in a competition. Not any more. I'm a father, I'm a husband, so many more things than just a diver."

Daley continued, saying his biggest achievement is "raising Robbie, just having him and Lance in my life."

After competing in four Olympic games, Daley finally won a gold medal Monday with partner Matty Lee in the men's synchronized 10-meter diving event in Tokyo.

"I thought I was going to win an Olympic gold medal in Rio, and that turned out the complete opposite by a long shot," Daley, 27, told reporters after winning. "And it was my husband who said to me that my story wasn't finished, and my son or child — we didn't know at the time — needed to be there to watch me win an Olympic gold medal."

He added, "I feel incredibly proud to say I am a gay man and also an Olympic champion. I feel very empowered by that."

Black, who was watching from Canada with their son and Daley's mother, took to Twitter to celebrate the victory.

"No words! So so many tears! @TomDaley1994 you're an OLYMPIC CHAMPION!" the screenwriter wrote.
