Over the years, Couture-Moncure has stepped into Leviss' life and is taking on that big sister role. The sisters have become close now, and Kate even planned Leviss' bachelorette party. She was even concerned that James, Raquel's fiance at the time, was very much overprotective and stern.

During her appearance on Watch What Happens Live with Andy Cohen in 2021, Leviss talked about her bond with Kate. She revealed that it is a sisterly love and Kate always wants what's best for Leviss. She also wanted to know if James was treating her little sister right, according to Bravo TV.
