Along with fellow Dance Moms alumni Chloe Lukasiak, Nia Sioux Frazier, Maddie Ziegler, and Brooke Hyland, Hilliker currently lives in Los Angeles. In October 2019, she gave fans a look at her new digs on her YouTube channel. "I can't believe I finally moved to LA! This has been a dream of mine ever since I was little and I am excited to start my next chapter of life!" Hilliker captioned the video. "I promise to take you guys along the way and enjoy this new and exciting chapter!"

Hilliker has dabbled in acting, with a leading role on the web series Dirt. She has also taken her love of fashion to the next level, designing a sock line called "Pretty Feet by Kalani" and collaborating with PromGirl to create a prom dress collection (via Woman's Day).

A prominent social media influencer, Hilliker has six million followers on Instagram and nearly one million subscribers to her YouTube channel. She uses her social media presence to share everything from her favorite fashion and beauty products to more serious topics like her ongoing struggle with anxiety. Hilliker recently shared that, after two years of stepping back from dance, she's rediscovered her passion. Hilliker said she danced as much as possible throughout quarantine and she looks forward to returning to studio classes once it's safe. She has recently begun to share videos of herself dancing on Instagram, and it's great to see Hilliker back in her element.
