Peggy Sulahian announced that she will definitely not be returning on Bravo's reality TV show "The Real Housewives of Orange County." In just less than a year after joining the cast, the Kuwait-born wife of custom-wheel mogul Diko Sulahian cited "moving on" as the reason for her departure after some self-introspection.

In an Instagram post, Sulahian explains her decision to her fans in a lengthy caption that reads: "It was an honor to be the 100th housewife and to be part of the Bravo family. I am extremely proud of being the 1st Armenian-American Housewife and sharing my culture with the world."

Sulahian is most remembered on the show for sharing details of her cancer scare that coincided with the passing of her father. In the same post, she said that she was able to reflect on her life after dealing with the disease and her father's death. Furthermore, she shared how grateful she was to have had the chance to share her story and how the show served as a platform for breast cancer awareness. Her biggest realization was the true importance of her health and being surrounded by people who love and care for her.

The 100th housewife hints at a new project coming her way by saying, "A few new ventures have availed themselves, and I look forward to sharing them with you soon!" This makes Sulahian the newest member of the "One and Done Club" among the Housewives.

Sulahian also made it a point to share her pride and pleasure in showcasing her love for her husband and three children, namely Giovanna, Gianelle and Koko.

It seems that changes abound in the upcoming 13th season of "The Real Housewives of Orange County" as other housewives have already announced their departure from the show early this year. Joining Sulahian in moving on are Meghan King Edmonds and Lydia Mclaughlin. As a result, many fans of the show have called for a casting "shake-up," so things still hang in the balance as there are still talks as to whether the "RHOC" will still be renewed for the next season.
