Kim Is Lost For Words As Khloe Goes All Out To Mark Kourtney Kardashian's 44th Birthday

Kourtney Kardashian is getting all the love from her family as she turns 44!!

The reality star enjoyed an avalanche of praise and adoration from her family, including Khloé, whose birthday tribute left Kim speechless. Despite that, the mother-of-four still posted a social media post acknowledging how special the celebrant was to her and the entire family. 

When April 18 rolled around, the Kardashian sisters rallied around their big sister, Kourtney, to celebrate her 44th birthday. Taking the lead in the festivities was Khloé, who shared a variety of multimedia, including clips from their famous "Keeping Up With the Kardashians" reality series, with 304 million followers. The mother-of-two partly effused in the caption:

"I have loved you before even knowing how to love. I have loved you since the moment we met and I have only loved you more with each day since. You will always be one of my best friends/favorite people in this scary world. But Life doesn't seem as scary when we are facing it together. What would I do without you?"

The post got the 38-year-old's Instagram fans gushing in the comments and struck a chord in Kim's heart. The California native promptly uploaded ten slides of some of her favorite memories from their childhood days, showing off that their bond began growing there.

While one photo showed Kim, Khloé, and Kourtney posing with their mom, Kris Jenner, at an old birthday celebration, another featured the celebrant holding Kim on the floor.

As seen in a subsequent slide, the doting big sis eventually got the SKIMS founder to lie down so they could kiss. The eighth pic in the fall highlighted the Kardashian sisters posing in front of a white vehicle, while the ninth saw them wearing gorgeous silver and white dresses at an undisclosed location.

In the final snap, Kim and her daughter North sat on an animal-print wraparound couch with Kourtney, her husband, Travis Barker, and a few members of their blended family. After admitting that she could not beat Khloé at the birthday caption game, the 42-year-old businesswoman wrote:

"I've just been sitting here trying to figure out how to express my deepest love for you and wishing you the most magical of birthdays. I treasure every single memory we have ever made and I can't wait to make so many more. I love you forever."

Fans quickly dropped their two cents in the comments, with one claiming that the "Ocean's 8" cameo star's "caption outdid Khloé's." Another fan admitted that although Khloé's captions are "undefeated," the one-time "Saturday Night Live" host's own was still "deep and heartfelt."

A few people also expressed disappointment that the Skky Partners founder did not include the clip of the celebrant slapping her in the Instagram post, while others gushed over their mom's tribute.

The Kardashian-Jenner matriarch Kris Jenner opened the tribute doors when she uploaded a montage from the day she and her late husband, Robert, brought their bundle of joy home from the hospital on Instagram.

For her caption, the momager noted that it still felt like yesterday that she welcomed her "beautiful firstborn child," adding, "I can't believe how fast time has gone by…I remember every precious, incredible milestone and how you came along that day and stole our hearts."

The post has received over 630k likes and nearly four thousand comments of support from her fans.

Just before her birthday, Kourtney marked the first anniversary of her impromptu Vegas nuptials with Barker. The Blast noted that the mother-of-three dropped a series of snapshots from the eventual day to Instagram, beginning with one that featured the happy couple standing at the altar.

Through other slides, viewers saw the "Kardashian Konfidential" co-author and her rocker beau inside a car before getting captured mid-kiss in front of flowy, white curtains. The couple ultimately shared a kiss in the presence of the wedding officiant, an Elvis Presley impersonator, who held a microphone in his hand.

The lovebirds donned matching black outfits and a pair of dark sunglasses for the ceremony. While Kourtney's leather jacket was designed with multiple metallic love shapes on the back, her husband's came with the inscription, "What Are You Staring At A**hole." In the caption, the "Kourtney and Khloé Take Miami" spin-off star recounted:

"It was one of the best nights of our lives, dreaming of a lifetime filled with fun adventures together. And yes, that's me about to throw up on the floor in the car," referring to a drunken selfie that highlighted her in the back of the vehicle.

The post has since amassed millions of likes from her fans and followers.
