"If you gonna act crazy and clingy of course he's gonna leave you. I mean you're not that hot that men would put up with that anyway."
Another evil troll then slammed Chelsie's appearance.
Chelsie kept her responses classy and sarcastically flippant.
"Honestly, thank you so much for your advice given that you knew everything about our relationship," she told one troll.
Adding: "Definitely not what happened but apparently you're an expert."
Chelsie then fired back about the troll's comment about her looks, writing: "That looks comment especially, I'll really work on that. Nahhhttttttt."
Thankfully, many of Chelsie's co-stars rallied around her, with Elly Miles, Jessica Brody and Emma Roche encouraging the chemical engineer to focus on herself during this difficult period.
"You are so strong and you never fail to blow me away with how amazing you are Chels. Anybody who knows you can see your value. You light up every room and I’m so grateful for your friendship. Also, I will literally fist fight anyone who’s a meanie to you," Jess wrote.
"You know what, some people just SUCK. They don’t know you, you are such a bloody angel Chels. You have a heart of pure gold & those who know you, know that & adore you for it 💛," Bachie fan-favourite Elly added.
