7 Shocking Milestones Kourtney Hit After Turning 40

She has embraced a new phase of life, often referred to by fans and the media as her "punk rock" era.

1. Getting Married to Travis Barker

Kourtney’s marriage to Blink-182 drummer Travis Barker was one of the biggest celebrity events of the 2020s. After years of an on-again, off-again relationship with Scott Disick, Kourtney found love with a long-time friend. She was 43 years old when she had her luxurious wedding ceremony in Portofino, Italy, in May 2022. This marked her first official marriage, a major life change that happened well into her fifth decade.

2. Welcoming a Baby at 44

In November 2023, Kourtney welcomed her fourth child, a son named Rocky Thirteen Barker, at the age of 44. The journey to conceive with Travis Barker was heavily documented on The Kardashians, involving IVF treatments and a significant focus on her health and wellness. This milestone was a powerful statement about her determination to expand her family later in life.

3. Defining Her Own Age Gap Narrative

Kourtney’s relationship with Travis Barker, who is 50 years old (born in 1975), has been a topic of public fascination. The age difference between the couple is approximately four years, with Kourtney being the younger partner. This relatively small age gap is often contrasted with the much larger age differences seen in other celebrity couples, allowing Kourtney to redefine what a passionate, mature relationship looks like in the spotlight.

4. Launching Her Wellness Brand, Poosh

Kourtney launched her lifestyle and wellness brand, Poosh, in 2019, shortly before her 40th birthday. The brand, which focuses on health, beauty, and lifestyle, represented her first major solo business venture outside of the family's collective enterprises. This move cemented her identity as a serious entrepreneur and wellness advocate.

5. Becoming an Executive Producer on 'The Kardashians'

When the family transitioned from *Keeping Up with the Kardashians* to their new Hulu show, *The Kardashians*, Kourtney and her sisters took on executive producer roles. This shift demonstrated a new level of control over their narrative and business dealings, giving her greater authority behind the scenes as she entered her 40s.

6. Publicly Prioritizing Health and IVF

Kourtney’s candid documentation of her IVF journey and subsequent natural pregnancy with Rocky at 44 normalized discussions around fertility challenges and late-in-life motherhood. This openness, especially in a family known for its carefully curated image, provided a refreshing and relatable look at the physical and emotional realities of trying to conceive in her 40s.

7. Embracing Her New Identity as a Barker

Since her marriage, Kourtney has officially adopted her husband's last name, often using "Kourtney Kardashian Barker" in business and personal life. This formal change, which occurred after she turned 43, symbolized a complete embrace of her new life, moving beyond the identity she held for decades as a single mother and a Kardashian. This transformation is a testament to her belief that the most significant personal chapters can begin at any age.
