The pop culture queen is turning 41 in 2021, and of course her family and closest friends took to social media to share their love and admiration.

Kim's iconic momager, Kris Jenner, was among the first to send her birthday message to Kim through her Instagram account. Kris wrote out a thoughtful and heartfelt message captioned underneath a decade's-old picture of the two together. Among the paragraph-long expression of her gratitude for Kim, Kris said

You are the most amazing mother, daughter, sister, auntie, and confidant. Thank you for this amazing journey we are on together, for being the most spectacular business partner, for chasing our dreams together and for each and every memory that we share together. I am beyond proud of you my beautiful daughter.

Also posting an adorable throwback, sister Kendall Jenner posted a couple Instagram stories of the two, showing teenage Kim holding baby Kendall. Kendall captured one of the photos "best buddies since the day I popped out!"

Newly-engaged sister Kourtney also joined in on the TBT train, posting an old VHS reel of the sisters putting on a performance when they were just kids. Kourtney additionally posted quite a few other photos of the duo, highlighting some of their most memorable moments together.

Among members of the Kardashian-Jenner clan to send birthday wishes, tons of her closest friends and standout celebrities also took to Instagram to show their love for the Skims founder. Kim's Instagram story is flooded with reposts of birthday messages, including some from designer Donatella Versace, her best friend Jonathan Cheban, and actress Cara Delevingne.

Kim is also using her national holiday as a way to promote some of her famous brands and companies. She took to Twitter to endorse her "Kim Kardashian: Hollywood" app, encouraging users and fans to join her b-day celebration virtually.

Happy Birthday, @KimKardashian! Celebrate with 25% off sitewide through Sunday, 10.24 at 11:59PM PT https://t.co/iOHzp1PH3J pic.twitter.com/618oP32a8k

The Twitter account for KKW Fragrance also announced a site-wide sale in celebration of Kim's birthday. The company is selling products for 25%, up until the end of the weekend.

Posts from the KKW franchise stand as testaments to just how successful Kim has grown over the course of this year, and especially throughout the growth of her career. Although all of society is more than aware of chokehold the Kardashian-Jenner empire has on the majority of pop culture, Kim's massive strides in her business ventures still can't go unnoticed.

Right before her first SNL appearance, Kim also made headlines with her ensemble for the 2021 Met Gala. Literally covered from head-to-toe in her custom Balenciaga outfit, Kim's Met appearance stirred up conversation surrounding her inspiration for the ensemble as well as the meaning behind it.

In addition to these most recent headlines, we can't forget about some of Kim's other noteworthy milestones from the beginning of this year. A huge success for both her and her company, Skims was awarded with the opportunity to partner with Team USA for the 2021 Tokyo Olympics. For the summer games, Skims produced a limited-edition collection of comfort clothes for the game's female athletes.

Equally-impressive, Kim started another business venture with her mom and sisters by trademarking Kardashian Kards. The new company, which was established during the beginning of 2021, is set to sell a wide variety of items such as stationary, photographs, and calendars.

Turning 41 also meant closing some other monumental chapters in Kim's life. Her divorce with rapper-producer Kanye West made massive headlines when the news broke earlier this year. Likewise, Kim also announced the end of KKW Beauty, revealing that a bigger-and-better beauty brand was in the works that would create improved products.

Also while still 40, the reign of Keeping up with the Kardashians came to an end with the family airing its final season this past year. As sad as fans might be to see the family go, they can still be caught in action in their new series. The Kardashian-Jenner clan is premiering on Hulu later this year, serving as a fresh start for the fresh 41-year-old.

40 undoubtedly had some crazy twists and turns for the social media mogul, and we can't wait to see what 41 has in store. Happy birthday Kim!
