Mary’s Early Life & Family Roots
Mary Jo Campbell was born on July 26, 1934, in Arkansas, before moving to San Diego, California, as a child. Her parents were Lou and Gordon Campbell, and she also had a half-sister named Frances (though some sources say her half-sister was named Lou).
From a young age, MJ had an interest in fashion, etiquette, and personal style. She wasn’t raised with cameras flashing or red carpets — she grew up in a time when family values, independence, and hard work were everything. And even though she’d later become part of the most public family in America, her personal charm always came from being down-to-earth and grounded.
A Young Model With Big Style
At just 15 years old, Mary Jo Campbell enrolled at Charms School Fashionality, where she learned modeling, manners, and grooming. She was a natural. With her refined taste and graceful presence, MJ became a model during her younger years. She wasn’t chasing fame — she simply enjoyed style, poise, and the joy of looking polished.
If you’ve ever noticed how elegant Kris Jenner or her daughters dress, that timeless fashion sense? It started with MJ. She set the standard — floral pantsuits, crisp coats, and her signature white-blonde bob haircut. Even in her 80s and 90s, MJ never stopped being effortlessly chic.
Mary Jo Campbell Marriage, Love, and Life Lessons
Mary Jo’s love life was anything but ordinary. At 18, she married her high school sweetheart, but the marriage lasted only two months. She once joked with Kim Kardashian that “history repeats itself,” since Kim’s short-lived marriage also made headlines. MJ simply realized that marriage wasn’t always “fun,” and she made the brave decision to walk away early.
Her second marriage was to Robert “Bob” Houghton, an engineer. They had two daughters — Kristen Mary Jenner (Kris) in 1955 and Karen Houghton in 1958. But that marriage also ended. When Kris was just seven years old, MJ and Robert divorced. Mary Jo found herself raising two daughters as a single mom, and she handled it with strength and grace.
Later, she married Harry Shannon, a businessman. This time, love lasted. They were together for 40 years until Harry passed away in 2003 following a tragic car accident. MJ always spoke about how hard that loss was, but she stayed strong — for her family and for herself.
Mary Jo Raising Kris Jenner & Shaping a Future “Momager”
Being a single mother in the 1960s wasn’t easy. But Mary Jo Campbell was determined to raise her daughters right. She taught them to be strong, smart, and self-reliant. Her daughter Kris, who later became the famous “momager” of the Kardashian-Jenner brand, often credits MJ for teaching her how to hustle, handle challenges, and care deeply for family.
MJ didn’t raise her kids to be celebrities — she raised them to be resilient women. Everything Kris learned about work ethic, managing a home, and handling life’s ups and downs started with Mary Jo. And that influence continued down the line — shaping the lives of Kim, Kourtney, Khloé, Rob, Kendall, and Kylie too.
The Birth of Shannon & Company
In 1980, Mary Jo opened her very own boutique: Shannon & Company, a children’s clothing store located in La Jolla, San Diego. She ran it for over 45 years, turning it into a beloved local business. It wasn’t just a store — it was where Kris Jenner worked as a teenager. It’s also where the Kardashian sisters played and learned about fashion and business as young girls.
MJ’s boutique taught them everything from folding clothes to managing customers to counting money. In fact, Kim once recalled how she would sit on the store floor, counting bills while singing, “Money is my name, and counting is the game.” That playful moment stuck — and so did the lessons.
Shannon & Company was more than just a job — it became the blueprint for how the Kardashian family would one day build their empire.
Mary Jo Campbell Becoming the Grandmother of America’s Most Famous Family
Today, Mary Jo Campbell is the proud grandmother of six world-famous grandchildren: Kourtney, Kim, Khloé, Rob, Kendall, and Kylie. And she’s also the great-grandmother of many little ones, including North, Saint, Chicago, Psalm, Stormi, and more.
But MJ isn’t just sitting in the background. She’s been featured on Keeping Up with the Kardashians, The Kardashians (Hulu), and in tons of social media posts. Fans love her quick wit, dry humor, and how she always brings calm to the Kardashian chaos.
One of her most iconic moments? Taking weed gummies with Kris and laughing on the couch with popcorn. Another? Comforting Kris during an emotional interview when Kris wanted to make a tribute video for her.
Mary Living Life Her Way in La Jolla
Even at 91, MJ continues to live life on her own terms. She still lives in her own home in La Jolla, just a mile away from Kris. Kris has tried many times to get her to move in — but MJ always says no. She loves her independence, her ocean views, and her peaceful lifestyle.
Every day, she talks to Kris on the phone. They chat about their day, what they’re watching on Dateline, and even what movie to put on if one of them feels sad. Their bond is sweet, fun, and full of love.
MJ’s Health Journey and Her Strength
As life went on, Mary Jo Campbell faced some hard challenges — especially with her health. But even when things got tough, she stayed strong. She fought and beat cancer not once, but twice. MJ survived both breast cancer and colon cancer, and she never gave up.
Her family often talks about how hard it was for her during those times. On Keeping Up with the Kardashians, Kim once shared that MJ had side effects from her treatments. Sometimes, the pain made her feel really sick. But MJ stayed positive and didn’t let it bring her down. That’s just who she is — brave, kind, and always strong.
Even now, at 91, MJ is still full of life.
Mary’s Special Family Moments and Birthday Love
Over the years, Mary Jo Campbell has been part of many happy family moments. One of the most touching was when she stood as a witness at Kourtney Kardashian’s courthouse wedding to Travis Barker in 2022. She was one of only two people there. That moment was very special to Kourtney, and she said she would never forget it.
MJ’s birthdays are always a big deal. In 2024, she turned 90, and the family shared sweet messages and old photos of her online. Then, in 2025, she had her 91st birthday, and they threw her a lovely garden-themed party. She wore a rose-covered outfit, smiled with joy, and posed for pictures with Kylie, Stormi, and the rest of the family. Everyone was so happy to celebrate her. The room was full of flowers, cakes, and laughter.
A Grandma Like No Other
Mary Jo Campbell isn’t just a grandma — she’s a role model. She teaches by example. She’s kind, honest, and always tells it like it is. The family loves her for that. Kris Jenner once said MJ is her hero and the reason she is the woman she is today.
MJ doesn’t mind joking around either. On The Kardashians, Kim once told her that she followed MJ’s advice and had a romantic moment by the fireplace with Pete Davidson. MJ just laughed and said, “I was young once too.” That kind of honesty and fun makes her even more lovable.
