So far, so intriguing – especially since it appears that their whole friendship group was in the know.
“They would hang out whenever she was in Newcastle, it was a legit thing, they were sleeping together, they were going on dates. It wasn’t a secret at all, all their inner circle knew about it,” Pustetto continued.
While it’s still not clear why the couple ended their fleeting romance (was it amicable or something more sinister?) one source claims Elly specifically asked Joe to join her for the season.
“It wasn’t a surprise at all, there was some acting involved because Elly actually requested that Joe be casted for the show,” So Dramatic revealed.
In a promo clip released by Channel 10, the mechanic can be seen greeting Elly, 26, and Becky, 30, in a black and gold checked shirt on his very first night in the mansion.
“No! It’s a small world!” he says, clearly shocked to two find familiar faces waiting for him at the end of the rose-lined red carpet.
Adding fuel to the fire, fans have also noted that Joe and Elly are following each other on Instagram.
“Oh what an iso crew,” Elly commented on one of his snaps, to which Joe replied: “@ellymiles just missing Dobby!”
It's safe to say the pair has serious chemistry but are they mates or something more? Tune in to Channel 10 at 7.30 pm on Wednesday to find out!
