Days before her birthday, Kardashian celebrated with a variety of fun cakes, including one with a cheeky cake topper that referenced a memorable moment from her family's reality show, Keeping Up With The Kardashians. The cake topper read, "Happy Birthday To The Most Exciting To Look At," a nod to a tense argument she had with her younger sister, Kim Kardashian, in which Kim accused Kourtney of not being as ambitious or influential as her.
“Kourtney is one of these people that just gets better with age,” the source said, reflecting on how much the star has changed on the heels of her turning 45. “As she’s getting older, things that mattered in the past, no longer [matter] to her.”
