If you remember, back when Chloe joined the show last series, there appeared to be sparks between her and Mario when they met at the gym.
Nothing happened, however, as Mario's happily loved up with British model Emma McVey.
Mario's still going strong with Emma but that doesn't stop Chloe's boyfriend Jake wondering what is going on when she chats with him at a club.
Jake had accused Mario of flirting with Chloe last series and made it clear he didn't much like the Italian tailor.
Unfortunately for him, Mario has said nobody will stop him speaking to Chloe as she's just a friend and nothing more.
He said in March: "I don't think I need to take a step back if I want to be friends with Chloe Lewis. It's friendship. We are friendly. It's not like we'll be best mates and going out, it will be very much, if I see her, I'll speak to her.
"It doesn't bother me, if Jake wants to get jealous with that or petulant about that, that's for him to deal with not me. Sorry mate."
Tonight's episode seems like it will be an explosive one for Chloe and Jake with trouble brewing just a few weeks after they rekindled their romance in Marbella.
As well as Chloe's chat with Mario sparking tension, she's left upset when she confronts Jake about photographs of him chatting to women at a recent party.
