Scheana Shayis friends with Kristin Cavallari and Stacie Hall of The Hills. On Tuesday, ahead of Lauren Conrad's anniversary special, the Vanderpump Rules starreceived a question from a fan about her relationship with her fellow reality stars. "Are[Kristin Cavallari]and [StacieHall]still friends?!" a fan asked Shay. In response, Shay told the woman, "We all are!"

During the final season of The Hills, Cavallari took over as narrator and Hall began appearing frequently due to her close relationship with her.

Meanwhile, during an earlier season, Scheana Shay made an appearance alongside her friend Hall, who began appearing on the show after Spencer Pratt flirted with her at her place of work, The Dime. Shay and Hall are extremely close friends and in addition to being in attendance during Shay's bridal party at Villa Blanca in Beverly Hills, California, Hall served as a bridesmaid during her July 27, 2014, wedding to husband Mike Shay.

Scheana Shay isn't the only 'Vanderpump Rules' star who appeared on 'The Hills'

During The Hills' six-season run, Scheana Shay's co-star, Tom Sandoval, was seen on the reality series. As cast members of The Hills, including the series' star, Lauren Conrad, attended a Teen Vogue casting call during season one, Sandoval briefly appeared on the show -- and he was shirtless.

Although Sandoval's guest starring role was short-lived, the moment proved to be a crucial turning point for Conrad's relationship with Jason Wahler on the show.

As fans of the series may recall, Conrad lied to Wahler about the casting and told him it was girls.

Kristin Cavallari is a fan of SUR Restaurant

Cavallari has been spotted at SUR Restaurant, the setting of Vanderpump Rules, several times and has even posed with cast members of the show, including Stassi Schroeder, Kristen Doute and Katie Maloney.

For more of Scheana Shay and her co-stars, including Jax Taylor and Lisa Vanderpump, tune into Vanderpump Rules season five.

The series will return to Bravo TV sometime later this year.
