Katy Kellner is an American fitness enthusiast, personal trainer, and former teacher who gained popularity after getting engaged to a professional NFL player, Shannon Sharpe.

Have you ever heard this line: Money and fame are very irrelevant and problematic?

The statement holds true for Shannon Sharpe, who apparently couldn’t protect his relationship with Katy Kellner.

No amount of money and fame can buy you your true love. Also, the thing about love is, it is sweet and happens instantly, whether one chooses it or not.

Here, we will not discuss about Shannon’s life but about his once-upon-a-time fiancee, Katy. Despite being inseparable initially, the couple saw life differently and decided to part ways.

Although the sudden breakup impacted Sharpe’s fame, Kellner definitely benefited from her short-lived fame and love life.

This article discusses the controversial yet beautiful Katy, her life, her relationship, and her current status!

Early Life, Education & Ethnicity

Despite her recent fame, information about Katy Kellner’s early life remains obscure. Therefore, we cannot provide you with her exact birthdate, information about her parents, or any possible siblings.

However, it is surprising that the internet has information about her educational background.

Kellner attended Elmhurst College to obtain a degree in Arts. Later on, she enrolled at Troy University, where she graduated with a master’s degree in Instructional Technology.

After completing her studies, she pursued a career as a local school teacher.

Age, Height, & Body Measurements

The beautiful Katy Kellner was born in 1981, making her 43 years old as of 2024.

Since Kellner has not disclosed her precise birthdate, there are no evident means to predict her horoscope.

On the other hand, Kellner doesn’t show any signs of aging, probably because of a healthy routine. To illustrate, she is a fitness instructor and trains her body regularly, followed by a nutritious diet.

Kellner’s never aging appearance might be the reason why Sharper caught the notice of the beautiful fitness guru.

Most importantly, Katy’s distinctive aspect is her brunette-gingerish hair, mesomorphic build, and square facial structure.


Katy began her career as a teacher at Fulton County Public School immediately after completing her Master’s degree from Troy University. She worked as an educator for nine years, serving the students of Fulton County.

What’s more fascinating about her is that, before getting engaged to Shannon, Katy was an ordinary woman who enjoyed her role as a teacher. She would bring food to the table and live off a teacher’s salary.

While there is nothing wrong with the profession, the public found it shocking that Kellner and Sharpe could have crossed paths without having any prior connections due to their different occupations.

Katy is a fitness enthusiast who ventured into the world of bodybuilding and made it her lifestyle.

Her career as a fitness expert has undoubtedly benefitted her in the long term. Kellner has worked as a regional director and was also a part-time instructor at Flywheel Sports.

At one point, Flywheel, a particular cycle bar, employed her as a regional manager. She also runs the Thousand Oaks Gym in California.

Net Worth & Income

According to reliable sources, it has come to our notice that Katy has accrued a staggering net worth of $1 million as of 2024.

Being a fitness advisor and amassing such a sum is commendable indeed.

According to the money.usnews.com website, a primary school teacher earns around $46k as a median annual salary, with the highest being $75k. She must have earned similar figures during her time as a teacher.

After moving to bodybuilding, Kellner reportedly received considerably higher wages.

As America is a country where gym culture flourishes every year, the number of gym-goers also increases. Taking into account the charges per person, the owner can foresee a high revenue every year. Hence, Kellner can pocket a hefty sum in a year alone.

Katy’s Thousand Oaks Gym charges $1.5 a day for a basic membership and $2 for the All-Access Membership, with the average per person spending totaling about $547.5 per year.

She also worked as a regional manager of Flywheel at Avalon, which might have also contributed to her net worth.

Finance, Personal Life & Relationships

To begin with, the American fitness expert came into prominence with her engagement to the famous former NFL Denver Broncos tight end Shannon Sharpe.

Shannon is regarded as one of the greatest tight ends of all time. He is also a former analyst for CBS Sports.

Sharpe has co-hosted “Skip and Shannon: Undisputed” on Fox Sports 1 alongside Skip Bayless since 2016.

Moving on, Shannon and Katy first met at the gym. As every love story goes, the two struck an instant fondness for each other.

After going on a few dates, the two reportedly engaged in 2016. Thereafter, the couple always traveled together at events, parties, or other gatherings.

However, all love stories don’t meet their happy endings; some end quickly, whereas others plummet to the ground.

In a shocking revelation, Katy was carrying someone else’s baby, and naturally, Sharpe severed ties with his partner.


Concurrently, in a now-deleted Instagram post, Kellner revealed the identity of her son’s father, who turned out to be none other than Marlon Byrd, the co-owner of Thousand Oaks.

Initially, everyone thought that Shannon was the baby’s dad, but the photo shared by Katy shocked everyone.

Marlon and Katy welcomed their son Jaden Charles Byrd on December 7, 2018. Sadly, the couple separated after some time.

Currently, Katy is happily married to Luis Castillo. According to available information, Luis is a policeman and also plays soccer.

She announced her engagement with Castillo via an Instagram post on January 10, 2021.

Katy and Luis reportedly tied the knot in July 2021. Luis took his Instagram to declare his wedding with his best friend and believes that he had done something good as he got to marry her.

Amid many controversies and past relationships, Katy lives happily with her son and husband. Luis also adores and maintains a good relationship with Jaden.
