Kelly Slater’s relationship with Kalani Miller is one of the most enduring and stable in the world of professional sports. The couple has been together for over 16 years, a testament to their deep connection and shared lifestyle rooted in the ocean. Miller is not just a partner to the surfing icon; she is a successful entrepreneur in her own right.

Kalani Miller co-founded the popular luxury swimwear brand MIKOH alongside her sister, Oleema Miller. The brand is deeply inspired by their upbringing in Orange County, California, and their extensive travels to coastal destinations worldwide. Kalani primarily handles the business side of the operation, while Oleema focuses on the design.

This new chapter with the arrival of their baby signifies a profound level of dedication and partnership. Kelly Slater is already a father to a daughter, Taylor Slater-Kelleher, from a previous relationship, who recently got married herself.

Why Hasn’t The Surfing Legend Married His Longtime Girlfriend?

The question of why Kelly Slater and Kalani Miller haven't married after nearly two decades together often resurfaces. The simple answer appears to be a mutual lack of urgency and a belief that their commitment is already complete without a legal document. Their relationship is a prime example of a modern, long-term partnership where traditional milestones are secondary to shared experiences and genuine connection.

A Modern Perspective on Partnership

In various interviews, Kalani Miller has addressed the topic of marriage with a relaxed and non-traditional view. She has suggested that their bond is strong enough that they don't feel the need for a wedding to validate it. They have built a life together that includes shared homes, business ventures, and global travel, all while maintaining their individual careers and passions. Their decision to have a child together, after so many years, is perhaps the clearest indicator of their commitment in the absence of a marriage license.

The Focus on Lifestyle and Surfing

Slater’s demanding career as a professional surfer, which requires constant travel for the WSL Championship Tour, has always been a central part of his life. While Miller often travels with him, the nomadic, competitive lifestyle is inherently non-traditional. Their relationship thrives on flexibility and mutual support, qualities that might be complicated by the pressures and expectations that sometimes accompany a formal marriage. Their focus remains on their lifestyle, their businesses (MIKOH), and now, their growing family.

Kelly Slater’s Relationship History and Family Life

While Kelly Slater’s current relationship with Kalani Miller is his longest and most public, he has had other significant relationships. Most notably, he was in a relationship with Tamara Michelle, which resulted in the birth of his first child, Taylor Slater-Kelleher. Kelly has often spoken about the challenges of balancing his professional surfing career with fatherhood, particularly the difficulty of being away from his daughter while she was growing up.

His daughter Taylor is now an adult, married, and has recently moved closer to him in Hawaii, indicating a strong and positive family bond. The surfing legend’s personal life, therefore, is not defined by a single marriage but by the deep, lasting relationships he maintains with his family members and his long-term partner. The impending arrival of his second child with Kalani Miller will add another rich layer to the family dynamic of the 11-time world champion.

Conclusion: The True Status of The GOAT’s Love Life

The answer to "Is Kelly Slater married?" remains a firm no, but the context is far more interesting than a simple yes or no. As of late 2025, Kelly Slater and Kalani Miller are one of the most stable and enduring couples in sports, having been together for well over a decade and a half. Their relationship is defined not by a wedding date, but by shared life, successful business ventures, and the joyful anticipation of welcoming their first child together. For the greatest surfer of all time, commitment is measured in years and new life, not in rings.
