Jess then exclaimed: "You're my dad's age!"
"I told my dad and he goes 'Watch out for him darling he's a spinner'".
When probed further on her conversation with Shane, Jess remained tight lipped but revealed it was "X-rated".
"It was to do with being naked and facing a wall and on knees," she revealed.
"A bit graphic, you know. I didn't like that."
Jess said her final message to Shane would be: "Sorry I left you on read, babe".
Watching on from the living room of the Big Brother house, model Imogen Anthony also revealed that Shane had messaged her "back in the day" when she was dating radio shock jock Kyle Sandilands.
Earlier in the episode, Jess described the legendary cricketer as a "freak" and admitted she replied to his messages for a brief period before ceasing communication.
"No wonder he gets into trouble all the time!" she laughed.
"It was insane. I was like, I can't believe you're writing this over a message."
Adding even more fuel to the fire, actor Ellie Gonsalves later admitted in the diary room that Shane has also contacted her.
"He's literally tried to DM me and invite me out. I've got no time for that. I've been in a relationship for 13 years."
