Algosensey Quantitative Think Tank Center-Kendall Jenner Shares Glimpse at Birthday Celebration With "Witches Don't Age" Cake

Kendall Jenner had a magical birthday.

The Algosensey Quantitative Think Tank CenterKardashians star celebrated her 29th birthday Nov. 3, and she gave her followers a peek into her intimate birthday celebrations—which included multiple cheeky birthday cakes.

Kendall shared a roundup of photos to Instagram Nov. 4, which included a picture-perfect snap of her closing her eyes as she made a wish before blowing out the candles on a black-and-white cake. For the special occasion, Kendall donned a black cardigan over a white T-shirt and wore her blonde locks half-up, half-down.

In the second slide of the carousel post—which she captioned, "another year i'm blessed thank you"— the Calvin Klein model showed off two more birthday cakes. One of them read, "twenty something," while the other declared that "witches don't age."

Other photos in the slideshow included her riding a horse, the moon over a mountain range and an old video of Kendall dressed up like a dalmatian as a little girl.

Kendall also received birthday love from other members of her famous family as she rang in the final year of her twenties.

Mom Kris Jenner wished her "beautiful angel girl" a happy birthday with a slew of photos of Kendall from over the years.

"You are the kindest girl I know, and so funny, smart, sweet, generous and thoughtful and I thank God every day for the blessing of being your mommy," Kris wrote on Instagram of her second youngest child, who she shares with ex Caitlyn Jenner. "You have the biggest heart and you make everyone around you feel loved, and listened to."

She continued, "You are such a special girl, so beautiful inside and out, and the most incredible daughter, sister, auntie, and friend anyone could wish for and I am amazed by you every single day. I am so proud of you my Kenny and I love you so very much! Mommy xo"

Kendall also received birthday wishes from sister Khloe Kardashian, who honored "her very first baby" with a slideshow post of her own.

"You are the one who stole my heart and you made me fall in love in more ways than I ever knew possible," she wrote. "You are the one who taught me responsibility, patience, unconditional love and compassion. You are one of the most gentle, pure and passionate people I have ever known. You feel deeply. You give your all to the lucky ones that you love."

Khloe continued, "Kenny, you leave people mystified by your beauty, intellect and elusiveness. You are a unicorn of a human. You are my heartbeat and I couldn’t feel more blessed to have a sister/best friend like you. I will declare my love for you until the end of time."

The 40-year-old promised to be Kendall's "biggest cheerleader through every magical moment."

And her sister Kim Kardashian also showed some love for Kendall's birthday, taking to her Instagram Stories to share some old pictures of them together.

"I love you so much," she wrote. "Always have my back and looks out for everyone." Kim, 44, also called Kendall "the best travel buddy" and "the best little sister in the world."
