Chrissy Teigen and John Legend are one of Hollywood's favourite couples.

The model and musician, who first met on the set of a music video in 2006, have been married for nine years and have two children with a third on its way.

Here's where it all began.

When John Legend and Chrissy Teigen announced their third pregnancy. Post continues below.

In 2006, Chrissy Teigen met John Legend for the first time on the set of his music video for the song ' https://www.youtube.com/watch?v=ZGC2Zk2fIOc https://www.youtube.com/watch?v=ZGC2Zk2fIOc Stereo'.

"I walked into John's dressing room to meet him, and he was ironing in his underwear," Teigen told Cosmopolitan in 2014. "I said, 'You do your own ironing!?' He said, 'Of course I do.' I gave him a hug."

After that, the couple spent the entire day together.

"We did the music video and then we were together for like 12 hours. We spent the entire day together, me in my underwear and him in a full suit. I went to go say goodbye to him, then to his hotel, and we didn’t ever say goodbye that night," she later shared with Wendy Williams in 2014.

After their first day together, the couple took things slowly.

"I let him be himself for a while," Teigen toldCosmopolitan. "The worst thing you can do is try to lock someone like that down early on, then have them think, 'There’s so much more out there.' I played it cool for a long time. Never once did I ask, 'What are we?'

"Marriage was never my goal because I’ve never been very traditional. I was just happy to be with him."

In a recent interview, Legend said he "wasn't a great partner" during the early days of their relationship.

"I think I was more selfish then," he said when appearing on the On Purpose with Jay Shetty podcast.

"I wasn't a great partner at the beginning of our relationship. Even though I was very into her and very excited to be with her, I was still selfish. I was in my mid-20s, still not ready to fully be the committed partner that I am now," he added.

"When you stop being so selfish when you think about not only the joy you get from a situation and the pleasure you get from it, but also think about your responsibility and your commitment in that situation. You just grow, and you mature."

In 2020, the singer also said that before meeting Teigen, he never seriously dated anyone.

"Yes, I did have a history of [cheating]. Definitely in my 20s," Legend told Dax Shepard on his podcast, Armchair Expert .

"I think what happened for me, you go through a lot of your life in your teens and I was younger than everybody in high school and college, and so I just didn’t get a lot of girls. When I started to get that attention, I loved it," he continued.

"But at a certain point, you just realise you’re happier being honest. You’re happier being faithful and being in love with one person. At a certain point, I just decided that person was Chrissy. I decided I wasn’t gonna mess with somebody else anymore."

In 2007, Teigen joined Legend on tour. But because of the stress and chaos of Legend's work life, the couple briefly broke up.

"I was on tour with him and he’d gotten sick," Teigen said. "He was feeling really bummed and stressed out. He was like, 'I can’t be in a relationship right now.' That lasted for one day. Literally, a day.

"I knew it came from a place other than us not working. It was the stress of him having to maybe cancel a show, and he had never been in a real relationship — or so he says now. I always joke, 'Remember when you tried to break up with me?' He’s like, 'Yes, sorry. Big mistake.'"

Months later, the couple took a holiday to their now-favourite holiday destination, Lake Como, Italy.

The same place they would later host their wedding and use as the backdrop for Legend's music video, 'All Of Me'.

After fours years of dating, Legend proposed to Teigen during a holiday in the Maldives in December 2011. However, before the proposal actually took place, there were a few mishaps.

"I remember we got into a very big fight in the car on the way to the airport because we had opened our presents beforehand, and he had only gotten me a cookbook and a Crock-Pot," Teigen told FABLifeShow .

"[The ring] was in my carry-on bag going through airport security, and security wanted to look through my bag and they wanted to look in that particular box," Legend later explained on Oprah’s Next Chapter in 2013.

"And Chrissy was standing right next to me and I was, like, 'Oh, my God. I’ve hid it so well this whole time but now as we’re just about to get to the Maldives she’s going to find out I have a ring in this box and it’s going to ruin the surprise and I’ll have to get on my knees in the airport.'"

But thankfully, the proposal went perfectly.

"We get to the Maldives and he had planned this beautiful Christmas. He knows how much I love Christmas... and this waiter comes out with a silver dome for dessert. So he opens up the dome and a ton of arugula falls out and then I kind of fish in it. And I see the little box and then you know, your heart stops and you get so excited," Teigen recalled.

"There was no big grand speech or anything. I think it was just very lovely and sweet."

In 2013, Legend performed his song 'All Of Me' on Oprah's Next Chapter. The hit single was written for his soon-to-be wife.

"I did cry when I heard it," Teigen told Huffington Post. "I’m emotional, but like I don’t really don’t cry at things like that so yeah, it was beautiful. And live it’s pretty unreal."

Later that year on September 14, 2013, the couple got married in Lake Como; after officially tieing the knot at the New York City courthouse.
