Cass was seen getting up close and personal with the professional dancer and was observed "stroking his face" by onlookers.
"When I met you I was classy and elegant,” Cass commented on one of Marco’s social media posts. “What the hell happened? You changed me ... and I’m not sure it’s for the better,”" she said.

Ditching her glitzy and glamorous stage outfits for jeans and a black singlet top at the afterparty, Cass also showed off her incredible figure and toned arms, which she puts down to eight weeks of dance practice and being a busy mum.
"I’m a busy single mum and don’t have time to sit still," Cass recently revealed on social media.
"Diet is also important to me ... eating what my body feels like but eating in moderation. I have also never owned weight scales. I monitor my health and wellbeing by how I feel and the way my clothes fit."
And while she may no longer be cha-cha-ing her way into our living rooms each week, this isn’t the last we’ll see of Cass.
Shortly after her elimination, Cass revealed she’ll now be a regular co-host on Studio 10 alongside Sarah Harris, Denise Scott, Joe Hildebrand and Angela Bishop.
"I’ll be working with Studio 10 on a more regular guest basis so that will be great," the author and journalist announced.
"It’s great and opens the opinions of more experienced women, I guess, that are around my ilk," she added.
Cass’ supporters, however, feel she has what it takes to take a job as top host.
"Hope to see you hosting TV show of your own. You have the background, ability and confidence," one of her followers shared on Instagram.
