The youngest of the Kardashian and Jenner empire premiered on Sunday the first episodes of her new reality series “Life of Kylie.” The show, a spinoff of the eponymous and wildly popular “Keeping Up with the Kardashians,” bills itself as a behind-the-scenes look at the intimate goings on of 19-year-old Kylie Jenner’s very public lifestyle.

As the daughters of matriarch Kris Jenner are wont to do, the Kardashian and Jenner sisters took to social media to celebrate the launch of their younger sister’s most recent brand extension.

Kim Kardashian, arguably the most visible player in the famous family, took to Instagram Sunday to shout-out the younger makeup maven. The 36-year-old posted a photo of the two embracing and captioned the image with a plug for E!, the same network that airs “Keeping Up with the Kardashians.”

“So proud of my little sis @kyliejenner She has her own show!!!! Tune in tonight on E!” she wrote. The post amassed nearly 2 million “likes” by Monday afternoon.

Kim Kardashian wasn’t the only one to give a nod to her little sister Sunday, as both Khloé Kardashian and Kourtney Kardashian shared their support on Twitter.

“Shine baby sister… #LifeofKylie starts tonight 9/8c on E!,” wrote Kourtney Kardashian. With her tweet she shared a photo of the two together.

Khloé Kardashian tweeted Sunday: “The life of Kylie is sooooooo good!!!!!”

While notably silent on Twitter and Instagram Sunday, Kendall Jenner did post a note of support for her sister August 4.

“so proud of my sister @KylieJenner... #LifeofKylie premieres Sunday at 9/8c on E!” she wrote in a tweet that was retweeted more than 4,000 times and “liked” by nearly 40,000 users.

For her part, momager Kris Jenner was busy on Instagram in the days leading up to the “Life of Kylie” premiere posting promotional materials for the new reality series.

Kylie Jenner retweeted the words of support from her sisters — as well as those of fans and family friends — on Twitter Sunday evening.

“I'm so so happy you guys love #LifeOfKylie thanks for all ur kind words!” she wrote Sunday for her 22 million followers on Twitter.

The two-part season premiere of “Life of Kylie” saw the entrepreneurial teen spilling for her fans some of the intimate musing that were promised ahead of its release. Perhaps most revealing, however, was Kylie Jenner’s openness about the way she viewed herself.

“There’s an image that I feel constantly pressured to keep up with,” she said. “In order to stay relevant for the public, I have to be on Instagram and I have to be on Snapchat just keeping people entertained. And then there’s who I really am around my friends. That’s who I want you guys to get to know.”

She later added, “I think I lost a lot of parts of myself. My funny side — when I was 14 I used to post all these funny videos all the time, just me being like, super weird and funny and myself. I feel like once I started getting a little bit bigger, then people really started to … everyone says mean things sometimes, it’s just how social media is — it’s a really mean, negative space.”
