School's out for the summer, and Kourtney Kardashian's daughter, Penelope Disick, is officially a sixth-grade graduate!

The Kardashians star shared the special news on her Instagram Story on Tuesday (June 3), revealing that her 12-year-old's latest milestone made her tear up.

"Me crying bc my baby girl is done with 6th grade (she's taking pics of me)," the Lemme founder explained aside a snap of her crying on her bed in cheetah pajamas.

Kardashian also shares sons Mason Disick, 15, and Reign Disick, 10, with ex Scott Disick (per E!News), and her youngest, Rocky Thirteen Barker, with husband and blink-182 drummer Travis Barker.

When her eldest was just four years old, the reality TV icon sat down with Harper’s Bazaar to discuss her favorite part about parenting.

"I actually think my favorite part is that you relive your own childhood. Going to Disneyland and watching all the movies I watched when I was a kid. I have so many of the books we read when we were little—so reading all the same books again. It’s really fun—you almost get to be a kid again and do all those magical things."

The mother of four is the first to protect her children from online rumors and keeps their privacy at the forefront. She has yet to share a photo of baby Rocky and plans to refrain from posting his face until he is of age to decide what he wants on the internet.
