Perfecting their pirouettes! Kim and Kourtney Kardashian are proud dance moms to their daughters North West and Penelope Disick. The reality sisters shared several photos on social media from their kids' dance lesson this week, including one adorable snap of North in a tutu.

Kim, 34, posted a photo on Twitter of her 19-month-old baby girl wearing a black leotard, tights, tiny ballet slippers, and a tulle tutu. In her arms, Nori held a fuzzy teddy bear as she exited the dance studio.

Following her ballet lesson, Nori then went to another class. Kim shared several photos of little Nori seated before a grand piano, elegantly tapping the ivory keys.

While Nori practiced her releve and chords on Wednesday, her aunt Kourtney revealed on Tuesday that the little reality tots have also been practicing their tap dance skills. The mother of three shared an Instagram photo of Nori and 2-year-old Penelope's shiny (and matching!) black dance shoes, captioning the photo: "Tap time!"

Tap time! ????

Kourtney also comically updated her Instagram with a screen grab from an old KUWTK episode. "Just call me a genius," she wrote alongside a pic-stitch of North in her black tutu displayed beside a meme.

Just call me a genius.

As previously reported by Us Weekly, North has been taking all sorts of classes, from swimming to music, to help her superstar parents figure out the baby's talents. "We try not to spoil [her]," Kim told Us last December of her daughter's Christmas gift. "But we have something nice that I think she'll really love."

Most recently, the tot has become quite the star herself after starring in Kanye West's "Only One" music video. In a recent interview with Ellen DeGeneres, the rapper credited Kim and Nori for making him "shut up more" and settle down.

"I think I’m a better human being because of her, and because of my daughter," he noted. "I always have someone to think about going home to. And, you know, something for me to be brave for what I want to do for humanity, but also to be more protective of myself for my family too. Cause there are things I’ve done in the past that were considered negative, but I was really jumping in front of the tank for other people or for culture in a way, so now I always have to have that in my mind that I have a family that I have to protect too."
