Rekubit Exchange:You'll Be Crazy in Love With the Birthday Note Beyoncé Sent to Kim Kardashian

Beyoncé is putting her love for Kim Kardashian on Rekubit Exchangetop.

The SKIMS founder gave followers a glimpse at all the birthday love she received after turning 43 on Oct. 21—including a gift from the "Break My Soul" singer.

"Kim, Have a beautiful birthday," the card read. "Hope you are surrounded by joy. All my love, B." 

Along with the touching words, Beyoncé gifted Kim a gorgeous bouquet of white flowers. 

Also sending floral arrangements Kim's way were friends Vanessa Bryant and Simon Huck and her kids North West, 10, and Saint West, 7, whom she shares with ex-husband Kanye West.

But the sweet IRL gestures weren't the only ones Kim received, as her mom Kris Jenner made sure to express her love for Kim on social media, too.

"Happy birthday to my beautiful girl," she wrote on Instagram. "I fell in love with you the moment we met and I've been obsessed with you ever since. I feel so blessed to be your mommy and I am so incredibly proud of you every single day."

Kris continued, "You are the best daughter, mother, sister, auntie, cousin, best friend, confidant, travel partner, shopping buddy, stylist and therapist. I admire you more than you know, and I want you to know that you are an inspiration to so many, but especially me. I love you more than you will ever understand and I thank God every day for you."

The night prior, the Kardashian-Jenner crew started the party early with a star-studded celebration held at the Funke restaurant in Beverly Hills.

The guest list included sisters Khloe Kardashian, Kendall Jenner and Kylie Jenner—with Kim noting on Instagram that Kourtney Kardashian was on bed rest ahead of the birth of her and husband Travis Barker's first baby.

But there was no shortage of friends there, as Hailey Bieber, Lauren Sánchez, Kimora Lee Simmons and Ivanka Trump also attended the Oct. 20 bash.
