Kourtney Kardashian receives loving Instagram posts for her 45th birthday

It's a very happy birthday for Kourtney Kardashian, who turned 45 on Thursday. Her special day was met with love and warm wishes from her loved ones on Instagram. Along with commemorative throwback photos, the captions additionally expressed Kourtney's essence and commitment to her family. It's a sweet way to honor the oldest Kardashian child.

Kris Jenner, Kourtney's younger sisters Kim and Khloé, and Kourtney's husband, Travis Barker, uploaded carousels filled with compliments and everlasting love. Kourtney radiates love whenever she can, as it spreads freely to others. To her sisters, her mother, her kids, Travis, her new son Rocky, and her friends all feel her aura.

Which is a must because why be negative?

Kris entered "proud mommy" mode when selecting the photos and creating the caption. The snaps chosen are childhood throwbacks, including one Kourtney used for the fifth anniversary of Poosh, and one with her late dad, Robert Kardashian. There are also snaps of a teenage Kourtney, being a mother, and at her Italian wedding.

In her caption, the matriarch described her eldest child as "a beautiful and amazing daughter, wife, mommy, sister, and best friend a girl could have."

Kim and Kourtney may have settled their most controversial feuds, but the younger sister has nothing but admiration for Kourtney. The proof is in the post!

Kim uploaded a photo of all three Kardashian sisters enjoying themselves in the ocean during their recent Turks and Caicos getaway. They all are sporting matching black bikinis as the sun pours down on them.

Kim called her relationship with Kourtney "the most magical journey" and reflected on their childhood days growing up.

Khloé, the youngest Kardashian sister, dropped a collection of sweet photos that elaborate on her and Kourtney's resilient sisterly bond. Inside her bundle, Khloé shared childhood throwbacks from the '80s and early '90s, when the sisters were prepping for the 2022 Met Gala, and a hilarious selfie with a giraffe at the zoo.

"My wish is that you continue to sparkle and radiate love and happiness," Khloé writes at the end of her warm caption. "I pray that the magic in you only gets stronger and the fire of life I see in you never ever dims."

Last but certainly not least is Travis Barker's birthday dedication. The famed blink-182 disclosed a couple of never-before-seen pics of Rocky Barker. The second slide reflects just that as a proud Kourtney gazes lovingly at her boy as they lie together in bed.

Than, there's a rather "cheeky" snap of Kourtney on the toilet. Now, I don't know if you'll agree with my ideology, but part of loving someone so deeply is knowing everything about them, including their bathroom habits.

In his words, Travis called Kourtney his "beautiful wife, soulmate, and best friend, and thanks the reality star for "being the most amazing wife a person could ask for."

We're not crying, you're crying.

How did Kourtney Kardashian celebrate her 44th birthday?

For her 44th birthday last year, Kourtney was gifted already with becoming a mom again, with her pregnancy with Rocky. But she also had a fun night out with her family by going bowling. Her sisters, her mother, Reign and Penelope Disick, her cousin Cici Bussey, and Travis were among the guests.

There was cake, friendly game competition, and reasons for celebration.

The Poosh founder wore a 1990s-inspired velvet outfit with her then dyed-blond locks in an updo. To top it off, Kourtney wore a silvery "Birthday Girl" crown.
