The photo showed the actress – who was formerly engaged to Home and Away star James Stewart – dressed in a pale gown.
On her knee sits Scout who is dressed in white, with flowers braided through her hair.
Jess clutches a bouquet of beautiful white flowers in the photo – which appears to have been taken on the beach.
Jess is thought to have been dating Sydney based photographer Jake Holly for around a year.
Fans of the Australian star were quick to say how happy they were for the star.
“It warms by heart seeing you smile. Bring on 2019,” wrote one fan.
“Immense love to you Sparkle soul!” wrote another.
And fellow Packed to the Rafters star Rebecca Gibney also shared a message.
“This makes me so happy,” she wrote simply, along with a love heart emoji.
