Fran, who now sports glossy brunette locks, posted the old photograph on Instagram this morning (15 May) for 'Throwback Thursday'.
In the snap, blonde bombshell Fran can be seen hugging her close friend and fellow TOWIE star Lydia Bright, who returned to the reality series last month.
Alongside the picture, Fran commented: "@lydiarosebright look what I found #TBT."
Meanwhile, it's a big day for Fran's TOWIE star boyfriend James 'Diags' Bennewith today - as it's his birthday!
In another tweet to both Diags and a male relative, who is also celebrating his birthday, Fran even used the 'L' word. Oooh!
"Want to wish my two fav men in the whole world a happy bday @DannyParman & @JamesBennewith love you both very much," she wrote.
TOWIE may be off our screens for the time being, but we're glad to hear that Fran and Diags are still going strong!
