“My beautiful granddaughter Penelope is officially a teenager,” Kris wrote, posing in one photo alongside Penelope and a much younger Kourtney“I can’t believe you are 13 today!”

The proud grandmother, nicknamed Lovey by her grandchildren, continued: “P you are such a smart, strong, confident, kind, fun, and amazing girl. You’re the best daughter, sister, granddaughter, friend, cousin, and niece, and you make all of us so proud every single day."

“You already have the most amazing sense of style and such a creative spirit. Getting to watch you grow into this amazing young lady has been one of the greatest blessings of my life, and being your Grandmother is a gift I cherish every single day. The world is yours my sweet P, and I love you beyond words!!”

Penelope – Kourtney and Scott’s middle child – has grown up in front of the cameras and is often seen on family trips or twinning with Kris – including in one snap where the pair sport matching lemon-printed dresses. She’s also been spotted at Beyoncé gigs with aunts Kim and Khloé Kardashian and cousin North West.

It comes just weeks after Kourtney, 46, got emotional over another big milestone: Penelope finishing sixth grade.

“Me crying bc my baby girl is done with sixth grade,” Kourtney admitted in a June 3 Instagram Story, joking: “She’s taking pics of me.”

The reality star, who also shares sons Mason, 15, and Reign, 10, with Scott and baby Rocky with husband Travis Barker, famously pulls out all the stops when it comes to marking her kids’ big moments. Last year she hired a Raising Canes food truck and a mechanical bull to celebrate the end of the school year, writing: “School is out!! Hello Summer!”

However, Kourtney who’s also stepmum to Travis’ children Atiana, 26, Landon, 21, and Alabama, 19 has admitted she doesn’t exactly rate the school system, calling it “so dated” during a chat with Khloé on her Khloé in Wonderland podcast.

“I love to go against the grain,” she said. “I think living authentically is not conforming… Let’s say the school system, I’ll think, ‘Why do kids f**king go to school?’ Truly, it’s so dated.”
