Shiloh Jolie is proving that hard work runs in the family!

On Saturday, Aug. 24, choreographer Kolanie Marks shared a video to Instagram, showing the 18-year-old daughter of Angelina Jolie and Brad Pitt busting a few moves as she gradually sharpens her dancing skills.

Marks, who previously spoke with PEOPLE about Shiloh's commitment "to a craft that is extremely hard," joked on Instagram that he's "officially her ADOPTED UNCLE" after her latest display of dancing chops under his tutelage.

Marks' latest video featured Shiloh dancing to Capella Grey, Jaewon and Young M.A.'s "Fly S—," as onlookers cheered her on. "I've watched this so many times and the confidence is growing and building! Keep going @sh1lohj I'm so so proud," Marks wrote in the caption that included a shout-out to choreographer Devin Solomon.

He also wrote on his Instagram Stories, "She's getting so good! I'm happy that she's sticking to the training!"

In July, Marks revealed in his interview with PEOPLE that he's worked with Shiloh for a couple years following their first class together at Millennium Dance Complex in Los Angeles. As he explained at the time, she's "dedicated herself to trying to figure out" his style of dance.

Marks, who has choreographed tours and music videos for artists like Mindless Behavior and Marques Houston, continues to post about Shiloh's progress on Instagram.

He told PEOPLE last month that their professional relationship is "very strictly based off of what we focus on, which is the dancing" and they don't discuss her famous family. Shiloh is the fourth-oldest child of exes Jolie and Pitt, who also share Maddox, 23, Zahara, 19, Pax, 20, and twins Knox and Vivienne, 16.

"I totally forgot who she is in that moment, because that's not what we focus on when we're training," he said of posting about her dance transformation. "I wanted to give her praise, of just the hard work and dedication that she puts in."

In July, Marks posted a video montage highlighting the rising dancer's commitment to the art form and her "doesn't quit" mindset.

"I'm proud and no we’re not done," he wrote of her growth as a dancer. "Give me til January!!!! I love to help dancers succeed!!! Many dancers/choreographers out now I've helped guide! All I need is trust and consistency and we will book!"

It's been a big year for Shiloh, who earlier this month was granted a name change. The teen filed to drop "Pitt" from her last name in May, and can now legally go by Shiloh Jolie as of August. A source close to Pitt told PEOPLE earlier this year that the actor was "aware" of the change, adding that he "loves his children and misses them."
