The reality stars were first spotted getting close on Eden's Instagram stories on Saturday as they partied the night away in Melbourne alongside Jessika's 'hot' brother Rhyce.
Romance rumours intensified when administration officer Jess and electrician Eden were also pictured enjoying themselves at St Kilda Festival on Sunday.
The TV personalities looked at ease in each other's company, smiling and dancing together for the camera.
Jessika was dressed to impress in a $240 mini-dress from Australian label Bec and Bridge which she paired with vertiginous gold stilettos.
The rising reality star put her own spin on the outfit by tucking the shoulder straps under the fabric.
She accessorised with statement gold earrings and a matching necklace, shielding her eyes from the hot summer sun with a pair of Raybans.
Also at the festival was older brother Rhyce who cut an aloof figure in a buttoned down khaki shirt and ripped black jeans.
The tatted-up 27-year-old, who works as a carpenter by day and a stripper by night, has been forced to defend himself against allegations he has been violent towards women.
Jessika's TV husband Mick reportedly spent the weekend at home on his farm in Gympie, Queensland.
