The Kardashians are pretty much the most famous family in the world. Between them have a fairly staggering bank account featuring eye-watering figures that many of us could only dream of. So, it comes as no surprise that when it comes to special occasions like birthdays - they tend to go all-out. After all, they are very rich, so there's basically nothing they can't have.

Yesterday, head of the Kardashian clan, Kris Jenner, celebrated her 64th birthday, and Kim Kardashian pulled off one of the most thoughtful and heartwarming surprises you could imagine. And of course, in true Kim-style, Kris' tearful reaction was captured for Instagram.

Keep scrolling to see how the star knocked it out of the park for her mom's birthday.

Kim Kardashian is a huge name in the celebrity world.

The Kardashian-Jenner family was propelled to celebrity stardom on their reality show, Keeping Up With The Kardashians and are now one of the most famous families in the world.

Despite gaining significant TV stardom...

The star has carved her own path beyond KUWTK.

Most notably, she's gone off on her own beauty-related ventures in recent years.

The mogul runs her highly successful beauty empire, KKW Beauty, and has established herself as a successful entrepreneur.

She is also a big player in the fashion scene.

The reality star has certainly not fallen short of head-turning fashion moments over the years.

And we can't forget the fact that she's now training to be a lawyer...

The internet was pretty shocked and confused when the star announced that she was heading to law school earlier this year. But, when you look at what Kim had been doing with herself in the months beforehand, it becomes pretty clear that she is genuinely passionate about criminal reform.

Over the years, on and off-screen, it's fairly obvious she is close with mom, Kris Jenner.

The pair clearly have a tight bond.

And let's be honest, if you've ever watched KUWTK, its obvious Kim is the favorite.

Remember when Khloe and Kourtney wanted to sue Kim over the whole perfume deal thing? Yep.

It's been the center of several jokes amongst the siblings.

Though the sisters have since admitted that the youngest of the clan, Kylie, may have taken Kim's crown as the golden child.

This week, Kris celebrated her 64th birthday.

And of course, Kim went all out with an extremely heartwarming surprise for her mom.

Birthdays in the Kardashian bubble are pretty extravagant as it is.

After all, when you have that kind of money, there's really no excuse for not going above and beyond.

Though it must have its downsides...

When you have the money to go and get whatever you want at the click of your fingers, we doubt the annual birthday wish list is really that big. What else could you possibly want?

So, this year, Kim opted for something more sentimental.

Yesterday, the star took to Instagram to reveal that she had a day of nostalgia planned for her self-confessed sentimental mom.

The beauty mogul tricked everyone into thinking that they were going out for a simple birthday lunch to celebrate Kris' big day, when, in fact, she had rented out their childhood home to host the lunch there. "Today we celebrate my mom. Anyone that knows her, knows how sentimental she is. For her birthday I planned a small lunch, with just her kids and her closest friends of 40+ years. "I sent out invites with a location where we all met. When everyone arrived, I told them I had a surprise and this wasn't where we would be eating. I then gave everyone the REAL invitation and once everyone saw the address for where we would be going tears filled the room," the star wrote on Instagram.

But it didn't end there.

Kim went as far as to have it decorated the same as when they used to live there - replicating the "ridiculous wallpaper and kitchen set" they had growing up. She also remade all of the table settings, decor, and wallpaper out of the same fabric and print.

Kim admitted that the day was emotional.

"We had lunch at the home as if it hadn't changed and we cried the entire time," Kim wrote on Instagram.

The big reveal was captured on video for Instagram.

And it showed Kris' tearful reaction to the thoughtful surprise and the moment she broke down after realizing she would be taking a trip down memory lane. "I rented our childhood home," Kim explained. "All of our memories live here, especially with our dad. It's where each Kardashian child was born and made us who we are."

The day also brought back a lot of memories of their late father.

"This was the best day ever. I am so proud I was able to keep such a meaningful surprise a secret from my mom and sisters for weeks! This was the most special, nostalgic day of my life and we felt my dad's presence enjoying this day with us!"

But Kim had another surprise up her sleeve.

"When we walked out to get our cars to drive there, I had another surprise! I had rented every car my parents ever owned. "I had some waiting outside so we could drive them to the house and the rest were lined up in the driveway of the house exactly how my parents used to have them parked. I even remade the exact license plates. (Yes my mom had a 2 DIE 4 license plate!) We drove to the home in these cars and relived our childhood!"

Kim admitted even she lost her composure during the day.

Not usually one for breaking down on camera, the star confessed to having a huge cry in the bathroom. "I kept it together and didn't cry the entire lunch even though I cried during the entire planning process. But at the end, I went into my old bathroom, closed the door and cried so hard," she explained.

After the day's celebrations came to an end, Kris took to Instagram to thank her daughter.

"I can't stop crying. This was the most magical day I can remember... Kim, you are an angel to all of us ... I can't express what this meant to me and I will now have this beautiful day to add to a lifetime of the most fabulous memories. I couldn't bear for it end," she commented on Kim's post.
