Thirsty for dramz, her fans voted overwhelmingly that she should attend, so she then went about her day getting prepped as any scorned ex would - first stopping off for a pedi, followed by a facial, then an eyebrow and eyelash appointment and finishing up with a blowdry.
She laughed as she claimed that she had all appointments "booked in before" she knew she was attending the same event as the vineyard owner and plant connoisseur. (Sure, hun.)
The I'm A Celeb star then had her followers help her choose from three brand new, chic outfits to make sure she looked her very best.
"We are both single, so we are going to have so much fun tonight," she said in a clip alongside her friend and plus-one, model Leah Jay.
Dressed to the nines, she also posed with a sign that read, "You could've had this."
In another clip, her insecurities shone through when she said she was feeling "a little desperate in the corner" of the party, as she waited for Jarrod to appear.
Playing out like an episode of Days Of Our Lives on her Instagram stories, she then shared the moment she was reunited with the man who she once said she wanted to marry and have babies with.
She called it a "stitch up" by the radio hosts who brought the pair up in front of the crowded room and tried to get them to hug.
But Keira didn't fall for it and ended up strutting away into the night.
Yesterday, in an awkward interview on the Fifi, Fev & Byron show addressed the split, saying that he's focusing on himself and that he hasn't spoken to Keira in two-and-a-half months.
When one of the hosts said that he saw Keira recently near Brighton in Melbourne, Jarrod added: "What is she doing in Brighton? I don't know why she's hanging out in Brighton, on Church Street - she doesn't live anywhere near there."
