Kourtney Kardashian is feeling all the emotions as her daughter Penelope Disick officially becomes a teenager. On July 8, the reality star and wellness mogul, 46, shared a series of sweet Instagram Stories from a family getaway in Italy to honor her daughter’s 13th birthday.

Alongside scenic views and glimpses of Penelope’s pink-hued cake topped with fresh berries, Kourtney reflected on motherhood, expressing that her “heart is exploding with gratitude and love” for her “sweet girl” who inspires her daily.

The milestone moment also carried deeper meaning, as Kourtney revealed the location was the same place her parents honeymooned nearly five decades ago.

The mom of four, who shares Penelope, Mason, 15, and Reign, 10, with ex-boyfriend Scott Disick, is clearly cherishing every moment of this new chapter.

Writing over a photo of a balcony view, she posted, “My daughter is 13 today. My heart is exploding with gratitude and love for her. I am so indescribably grateful for my sweet girl. She inspires me every day to be a better person.”

Another Story featured Penelope’s beautiful birthday cake: a light-pink iced creation decorated with hand-piped purple lettering that read “Happy Birthday Penelope.” The cake was surrounded by an assortment of fresh berries, including strawberries, raspberries, blackberries, and blueberries.

Kourtney, who married Blink-182 drummer Travis Barker in 2022 and shares a two-year-old son named Rocky with him, also noted a special family connection to the vacation spot: “My parents spent their honeymoon here 47 years ago, so special to get to bring my daughter here.”

Penelope’s grandmother, Kris Jenner, 69, also celebrated the occasion with a loving tribute on Instagram. Posting a carousel of photos spanning Penelope’s childhood, including sweet moments with Kris, she wrote, “My beautiful granddaughter Penelope is officially a teenager!! I can’t believe you are 13 today!”
