Its the end of an era.

Shortly after it was announced that Vanderpump Rules would be returning for a 12th season with an entirely new cast, many of the OGs took to social media to react to the bombshell.

vanderpump rules, you will forever be that girl i was up til 4am looking for all the right pics and the right words, but theres no post or caption that could ever encapsulate everything, Ariana Madix captioned a carousel of photos from her time on the show on Tuesday.

i am forever grateful to have been a part of such an incredible cultural phenomenon. thank you @bravotv, @lisavanderpump, @evolutionusa for every experience over the last 10+ years.

Madix  who joined the show in Season 2  noted that although she will miss every single crew member, producer, and our showrunners they have her phone number so they can just text me.

The 39-year-old also thanked the fans for tuning into the show and supporting her and the cast before she concluded the post with a heartfelt closing statement.

Im feeling at peace with closing this chapter and im excited for everything that is to come. i dont know that these were the best days of our lives, but they were definitely something special , Madix wrote.

Lala Kent  who joined Vanderpump Rules in Season 4  also took to Instagram to pen a goodbye letter to her time on the show.

Where to begin. I was a young girl from Salt Lake City who made her way to L.A. I would introduce myself as Lauren, but because my childhood best friend referred to me as Lala, my nickname quickly stuck, she wrote in the post shared Tuesday.

Sur was a place that became home. I found myself not only sipping on vodka sodas there, but behind a hostess stand it still to this day is the most intimidating job Ive ever had.

A short time later the opportunity to be on a show called Vanderpump Rules landed in front of me. I have such mixed feelings right now. Its no secret I do not like change. This is the exception, Kent, 34, continued.

Kent concluded her post by thanking the fans for rocking with us and for changing her whole life.

We rocked this bitch until the wheels fell off , she gushed.

Katie Maloney  who joined the cast of the show in 2013  wrote on her Instagram Tuesday that her time on the show was a mixed bag.

But I wouldnt change a thing. Thank you for the memories and the love the last 11 years, the 37-year-old wrote.
