Fans have been incredibly excited.

But the person who is perhaps the most excited?

Little Luna, of course!

It seems that Luna is very eager to meet her new brother or sister...

And she has been making sure her mom takes things easy at all times.

Now, Chrissy Teigen and John Legend are Hollywood's sweethearts.

The pair got together over a decade ago and have gone from strength to strength ever since.

Their romance began in 2007.

Chrissy and John first met on the set of his 2007 music video for “Stereo," where she starred as the singer's love interest.

But, the pair didn't make it official until months after a music video fling.

With John heading out on tour shortly after wrapping up his music video, the timing just wasn't meant to be. “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," Chrissy explained to Cosmopolitan in 2014.

While John was on the road, the couple talked and texted religiously...

But it wasn't long before Chrissy joined her beau on tour, although the pair had a mini-break up during this time... that lasted a day. “I was on tour with him and he’d gotten sick," she explained. “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."

Fast forward 4 years of dating and John was down on one knee...

"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," Chrissy explained.

The pair got hitched on September 14, 2013, in Lake Como.

But they (legally) got married in an NYC courthouse, a day before traveling to Italy.

They have since cemented themselves as a firm Hollywood power couple.

The two are a pivotal part of the celebrity scene and their fans lap it up (especially where Chrissy's relatable social media posts are concerned... let's be honest, she's comedy gold!)

All in all, they are truly relationship goals...

And their little family is simply the cutest.

The couple share 2 children together...

Chrissy gave birth to their daughter, Luna Simone Stephens, on April 14, 2016, and son, Miles Theodore Stephens, on May 16, 2018.

Chrissy regularly posts about family life on Instagram...

And by that, we mean she posts the ins and outs of being a mom.

She's known well for her honest perspective into parenting...

And she perfectly outlines the tiring but wonderful experience of raising 2 young children.

And it looked like things are going to get even more tiring...

Because they're expecting their third baby!

Yep, they made their exciting announcement last month...

Via music video, of course. The video was for John's new track, "Wild", and it showed the couple frolicking around on a white linen bed on the beach.

Some of the lyrics include:

"I wanna drive you wild, wild, wild. I wanna love you for miles and miles. We can go slow, we don't need to rush. I'll take the wheel, make you feel every touch. I wanna drive you wild, wild, wild."

But, as the song draws to a close...

We get an unexpected, yet very exciting shot of the pair.

A pregnancy bump!

Yep, the Legends are officially going to be a family of 5, and we couldn't be more excited.

At the end of the video, their 2 other children join in the fun...

And they all walk towards the ocean together as a family.

It's a beautiful video...

And clearly, the family is overjoyed with the news!

Of course, Chrissy is now facing a tiring 8 months...

Because we all know how tiring it is to be pregnant! But luckily for her, 4-year-old Luna is on hand to make life as easy as possible.

Luna was very hands-on at the ultra-sound...

And she even held the transducer over her mom's stomach that allowed the family to see the outline and heartbeat of the baby!

She then made her mom and dad an adorable anniversary card...

Which was the cutest thing ever!

But now, Luna has decided to take things to the next level when it comes to looking after her mom.

At the moment, Chrissy is on "super serious bed rest" due to a weak placenta and little Luna has been running around making sure her mom doesn't lift a finger.

Luna has been running baths for her mom every day...

And Chrissy shared an adorable snap of Luna washing her hair. "Every day she makes me a warm (not hot, chill!) bath and refuses to let me wash my own hair 😩 girls, man. @johnlegend how did we get so lucky with lulu??" she wrote.

Here's the adorable post:
