Kim Kardashian and Kylie Jenner's successful careers and business are all possible -- thanks to their business-savvy and loving momager, Kris Jenner, who celebrated her 64th birthday recently. Here’s how the famous Kardashian siblings made their mom’s birthday a bit more special.

Kylie Jenner treated her mom to some cruise and lunch on her birthday on Tuesday, according to Daily Mail. The “KUWTK” stars went for a leisurely ride in a convertible with the top down before they met up with Kylie’s siblings for an outdoor lunch.

Kylie posted a few photos documenting the small gathering. In one picture, Kris can be seen blowing the candles on a driver’s license themed birthday cake with the words “2 DIE 4” on it.

She also honored her mom’s birthday by giving a hefty discount to customers of Kylie Cosmetics, according to PerezHilton.  The youngest self-made billionaire tweeted that buyers can get Kris Collection at a bargain.

“Happy birthday @KrisJenner _ we're celebrating at @kyliecosmetics with 50% off Kris Kollection TODAY ONLY,” Kylie posted on Twitter.

Kim Kardashian posted a sweet message on Instagram to celebrate Kris' birthday. The reality star posted a photo showing her and Kris with a caption thanking her mom for being the best mom and manager.

“Happy Birthday mama!!!! Today is your day! You are the best mom in the entire world,” Kim captioned the photo. “You’ve given us the tools to be the best we can be and have taught us that kindness rules the world.”

Meanwhile, Kourtney Kardashian opted for a more fun way to greet her mom on her birthday. She posted a short clip of Kris singing karaoke Kanye West’s song “Mercy.” The video was captioned, “Happy birthday to the queen of everything (karaoke included).”

Khloé Kardashian, on the other hand, posted several iconic Kris moments taken from “KUWTK.” In one clip, Kim was being scolded by their mother for being too busy taking selfies even as her sister Khloe was apprehensive over the prospect of going to jail.

“Kim, would you stop taking pictures of yourself? Your sister is going to jail,” the Kardashian matriarch said in the video.

Supermodel Kendall Jenner opted for something short but sweet. She uploaded an old photo showing herself when she was still a baby being held lovingly by her mom and captioned the post with “happy birthday momma.”
