Reports surfaced recently suggesting Marnie had locked lips with her former flame and now, the 23-year-old has admitted she and Aaron did kiss again.
Although, she has assured it had happened once she and Ricky Rayment had split.
Speaking to The Mirror, Marnie set the record straight on rumours circulating the break down of her and former TOWIE star Ricky's relationship.
She told the paper: "There's a lot of stories going around, I kissed like three people - it's all lies. I kissed Aaron from the show that's the only person I kissed."
"I had a few ups and downs with other people, but that's the only person I actually kissed," she continued. "I wasn't actually with Ricky at the time."
Reports had suggested the kiss took place while Marnie and Aaron were attending a PA in Italy with their Geordie Shore co-stars. On hearing about the kiss, Ricky, who had been contemplating getting back together with Marnie, was said to be "devastated".
Marnie reiterated that her kiss with Aaron was the final straw for Ricky, adding: "We were texting and we were going to work things out.... but that made him not even want to try again.
"Obviously he didn't and that's fair enough, but I think in my head we weren't together for a reason."
Soon after, Ricky told his followers on Twitter he was "moving on". That was after he cryptically tweeted: "That's what happens when you think u can trust your pals with your code! #donttrustanyone."
Trouble between Marnie and Ricky first surfaced at the end of August, just two months after the couple announced their engagement. Marnie has since confirmed the pair's break up, admitting she is "heartbroken".
She said: "The official end to a very important chapter in my life. Thinking positive brings positive things. Moving forward to the future... Everything happens for a reason. If something isn't meant to be, it won't be."
More recently,Marnie was forced to deny speculation she and Ricky are getting back together.
After attending the same party together, the ex-couple had people talking of a reunion when things seemed pretty amicable between the pair. Marnie, however, has insisted she and Ricky won't be giving their relationship another go.
"There's no chance that we're going to get back together because I know that he knows we aren't right for each other," she said.
"I'll always love him and I'll have so much respect for him forever and I was engaged to him, so that means a lot to me."
