Kim Kardashian posted a birthday tribute to her younger sister Kylie Jenner on Tuesday, two days after Kylie’s actual birthday on August 10. The message went up on Instagram with unmistakable warmth. It called Kylie her “princess kitty baby sis” and closed with an enthusiastic declaration of love: “I lovvvveeeeee youuuuuuuuu.”
Kylie Jenner turned 29 this year, born on August 10, 1997. Over the past decade, she has built one of the more recognizable cosmetics lines in the industry. Kylie Cosmetics launched in 2015 with a single lip kit. It has since grown into a full beauty line available through major retailers globally. Jenner’s success with the brand was an early signal. The next generation of the Kardashian-Jenner family was clearly carving out its own business identity.
Kim, meanwhile, has remained one of the more consistent public figures in the family’s collective enterprise. Her shapewear and apparel brand SKIMS launched in 2019 and has grown into a notable player in the category. It has earned consistent attention for its approach to inclusive sizing. The two sisters each built a broad social media presence first, and used that foundation to move into retail and licensing.
The nickname “princess kitty baby sis” generated interest in the comments. It has the feel of private family shorthand surfacing in a public place, offering a glimpse into the informal dynamic between the two. That warmth contrasts with how both women typically present their professional work. Their brand rollouts tend toward polished visuals and carefully sequenced announcements, not playful nicknames.
The tribute collected around 236,000 likes on Instagram. That number falls within a typical range for personal content on an account of Kim’s size. It reflects the consistent audience interest both women generate, rather than any particular viral surge.
Kim and Kylie have appeared together frequently on Hulu’s “The Kardashians.” The show is now in its later seasons on the streaming platform. It has tracked the family through professional milestones, personal challenges, and quieter everyday moments. Their on-screen dynamic tends to be warm and close. The series also doesn’t avoid the complications of family life in the public eye.
The two-day gap between Kylie’s birthday and Kim’s tribute is not unusual. Social media posts within the Kardashian-Jenner family often arrive in waves over several days around a birthday. Kylie herself is active on Instagram and regularly documents her professional and personal life there. A delayed message from an equally busy sibling is easy enough to understand.
At 29, Jenner is at an interesting stage in her career. She has a decade of entrepreneurial experience, a global cosmetics brand, and a growing public profile. Kim’s birthday message was brief. But it was genuine, and it put the warmth of the sisters’ relationship on clear display.
