Marnie's only just returned to the house - to the delight of everyone, especially Aaron - and it looks like we'll see romance blossom between the pair again.
A sneak peek of the next episode was teased at the end of last night's show, and Marnie drops the L-bomb to Aaron.
Here's the exchange below:
Aaron: "Do you want to be single or on the pull?"
Marnie shouts: "No! I love ya."
Aaron says to the camera: "You what?!"
During Tuesday's episode we saw Marnie and Aaron reunite. She left the house in the last series following her engagement to ex-TOWIE star Ricky Rayment in Greece.
But with Marnie now returning as a single girl, she and Aaron instantly picked up where they left off. Despite her not being too happy about his wrist tattoo of Chantelle Connelly's name, Marnie and Aaron flirted in a club before kissing in bed when they got back to the house.
Marnie has since revealed that she could see them becoming an official couple.
"I'd like to think we could [be official one day]," she told Mail Online. "We both need to stop playing games and take the plunge."
