The gang headed out to the Spanish city last week to film scenes for the brand new series, and Jess and Pete have been spending some time together.
A source told The Mirror: "Jess and Pete have been growing close for a while but while they keep on insisting their relationship was purely platonic, things really heated up in Marbella. They shared a kiss but it looks like the holiday romance could be one that comes home with them."
This new report comes as Jess admitted that Pete had visited the hotel room she shares with Danielle Armstrong and Ferne McCann.
"Peter Wicks was not in this room on his own," Jess insisted in a new TOWIE video. "I was with a group of people. Just to clarify."
Jess met newbie Pete in Marbs ahead of the last series, and there appeared to be an instant attraction. The pair flirted and discussed their pet dogs, eventually going on a date back in Essex.
However, they decided not to take things further and just remain friends. But by the end of the last series Pete storming off after Verity Chapman quizzed him about rumours he'd been flirting with Jess.
