During his time on Vanderpump Rules, Jax Taylor introduced viewers to several of his family members — from his mom, Marie Cauchi, to his younger sister, Jenny Lynn.
After Jax's father, Ron Cauchi, passed away in 2017, The Valley cast member got even closer with his sister. She even attended the soft opening of his bar, Jax's Studio City, on The Valley Season 1 finale (which aired back in June 2024).
Fast-forward to February 2025, and Jax just shared an update on his relationship with his sister on his Instagram feed.
"My beautiful sister [Jenny Lynn] . Not sure what I’d do without ya..." he wrote alongside a photo of Jenny wearing a black Gucci crossbody that Jax gifted her. "I don’t know anyone that’s more hardworking and deserving than her..."
Jenny replied, "My first Gucci..." underneath her brother's post.
Inside Jax Taylor's special bond with his sister, Jenny Lynn Cauchi
Jax and his sister have gotten so close that he played a very special role in her 2018 wedding.
The former SUR bartender walked his sister down the aisle for her May 2018 nuptials, which took place about five months after their father passed away.
Jax shared a photo of an empty chair, which was reserved for Ron, on the day of the ceremony.
"Right where you should be pop, front row, watching your little girl get married today. (I received my father[']s ashes today for the first time and will be carrying them in one hand and walking my sister with the other)," he shared.
He continued, "I love and miss you so much pop, please help me guide Jen down the aisle today, help us be strong today, it’s going to be emotional as hell but I promise I won’t let you down, I know you are watching over us today, and don’t worry not taking your place just filling in for a minute. We love you dad!"
Jax's estranged wife, Brittany Cartwright, served as a bridesmaid on the big day.
When Jax and Brittany tied the knot in Kentucky just over a year later, Jenny was there to return the support — even though their mom did not attend.
She posted the above photo on her Instagram Story, writing, "[Jax Taylor,] love you." She also shared a picture with Brittany and referred to her as her "new sis."
Jax and Brittany separated in February 2024, and she filed for divorce in August.
