Chrissy Teigen and John Legend just announced the birth of their fourth child meet their family

They tied the knot seven years after meeting on the set of Legend's music video for the song "Stereo" in 2006.

"We did the music video, we were together for like 12 hours," Teigen told Wendy Williams in 2014, Insider previously reported. "We spent the entire day together, me in my underwear and him in a full suit, and I went to go say goodbye to him, to his hotel and we didn't ever say goodbye that night."

In 2013, they got married in a lavish ceremony at Italy's Lake Como.

"One of the first vacations we took together was to Lake Como, so we thought it would be nice to marry where we fell in love," Legend told Martha Stewart Weddings.

"John and I are so happy to announce that we are pregnant :) As many of you know, we've been trying to have a baby for a while now. It hasn't been easy, but we kept trying because we can't wait to bring our first child into the world and grow our family," Teigen wrote on Instagram in October 2015.

In 2018, Teigen spoke with The Cut about her experience with IVF, or in-vitro fertilization, and how it was "devastating" when it didn't work the first time.

"The first round I did of IVF, when it didn't work, I remember thinking, 'Oh, I was on my feet too much, and that's why.' You just look for anything to blame, especially yourself," she said.

"There's no right way to do IVF. You just have to keep hoping that it will happen. It's easy for some, and not for others. And that's okay," she continued.

Luna, who is now 7, regularly makes appearances in her mom's Instagram photos, along with her siblings. She has appeared in music videos, including for her dad's 2016 song, "Love Me Now."

Teigen publicly announced that she was pregnant with Baby No. 2 in November 2017 with a video of Luna pointing at Teigen's stomach and saying there was a baby in there.

Six months later, Teigen tweeted that her son had been born with a simple "Somebody's herrrrrrre!" accompanied with emojis.

"It's [very] difficult right after delivery for a woman. A lot of women deal with postpartum depression. There's a lot going on with your body and your hormones," Legend told E! Online in 2021.

"As a husband, we've got to be reliable. We've got to be a rock. We've got to be there for our wives. We've got to be as present and available as possible to help with whatever needs to be done," he said.

Miles is now 5.

In August 2020, Teigen and Legend announced she was pregnant again in the music video for Legend's song, "Wild."

But a month later, Teigen posted from the hospital that she'd been admitted after heavy bleeding.

On September 23, 2020, she wrote, "We are shocked and in the kind of deep pain you only hear about, the kind of pain we've never felt before. We were never able to stop the bleeding and give our baby the fluids he needed, despite bags and bags of blood transfusions. It just wasn't enough."

Two years later, Teigen shared that what she had called a miscarriage was actually an abortion, and it saved her life.

"Two years ago, when I was pregnant with Jack, John and my third child, I had to make a lot of difficult and heartbreaking decisions," she said, according to The Hollywood Reporter. "It became very clear around halfway through that he would not survive, and that I wouldn't either without any medical intervention."

"Let's just call it what it was: It was an abortion," Teigen continued. "An abortion to save my life for a baby that had absolutely no chance."

"The last few years have been a blur of emotions to say the least, but joy has filled our home and hearts again. 1 billion shots later (in the leg lately, as u can see!) we have another on the way," Teigen wrote on Instagram in August, confirming that the couple had used IVF again.

"Every appointment I've said to myself, 'ok if it's healthy today I'll announce' but then I breathe a sigh of relief to hear a heartbeat and decide I'm just too nervous still," she continued.

In January 2023, Legend told fans during a concert that Teigen had given birth to their daughter Esti.

"What a blessed day," he said, according to People, after telling the crowd that they welcomed "the little baby this morning."

Just five months after Esti was born, Legend and Teigen surprised the public by announcing the birth of their fourth child, Wren, via surrogate.

"Wren Alexander Stephens, our new love," Legend wrote on Instagram, alongside a photo of him with his four children.

Teigen wrote about their journey with surrogacy, something they hadn't been public about.

She explained how she had always wanted four kids, and that after her miscarriage in 2020, she wasn't sure if she'd ever get pregnant again, which led to the couple exploring surrogacy options.

At the same time as their final try with IVF that led to Esti, they met "the most incredible, loving, compassionate surrogate we could ever imagine." That led to the birth of their son, Wren.

"Our hearts, and our home, are officially full," Teigen wrote.
