In the photo, Savannah rocked dark hair which she wore loose with bangs.
Fans went wild for the photo and commented: "How wonderful is that," and another added: "This is amazing," while others said they didn't think she had changed and told her, "you look the same".
Savannah hit a major milestone recently when she turned 50 in December - and she's never felt better.
Savannah was surprised with her old yearbook photo
She marked her 50th year with her close family, including her husband and their two children at home as she celebrated her birthday just a few days after Christmas.
While it was a "perfect" birthday, the star admitted that it was bittersweet in a heartfelt post at the time, as her late father was constantly in her thoughts – having passed away at the age of 49, and never making it to her current age.
She wrote: "I was surrounded my dearest. My husband who treats me like a treasure… my darling angel babies… and the three who were there with me at the beginning…on this day 50 years ago today. Mom, Cam, Annie.

"So I treasure this gift of life and remember you always. And thank god for a half century of His kindness and grace and blessing," she concluded.
