Sam made the confession on last night's episode of TOWIE (9 June) as she tried to work out what exactly Joey had told his cousin Chloe Sims about her.
Bizarrely, she then told sister Billie and close friend Fern that "everyone has slapped their boyfriend".
While sitting in a spa, Sam admitted: "Whatever he's said, he's obviously exaggerated and fabricated it. I can't think of one thing that stands out which is really bad, apart from when we were in Dubai.
"We had a massive row, I pushed him and slapped him around the face. That's the only thing I've ever done...like once in one whole year."
Sam then told Billie and Fern: "Everyone's slapped their boyfriend around the face at one point, or if they deserve it - do you know what I mean?
"Like, it's only a slap. I wouldn't have done it for no reason."
Meanwhile, a forlorn looking Joey was shown chatting about his and Sam's break-up to Chloe, Frankie and Dan on the grass at Arg's BBQ.
While he stared at the ground, Chloe told him: "At the end of the day Joe, the main thing that everyone wants is for you to be happy and content. In Spain, you were anxious and upset. You seem more relaxed but I don't think you're back to yourself yet.
"It is hard Joe, it's not going to be easy. Break-ups are the worst. But every day will get easier. Whatever makes you happy, do it."
But despite what viewers have seen, away from the TOWIE cameras, it appears that Sam and Joey could have already kissed and made up.
The pair were spotted having dinner together at a local restaurant in Essex last night and, although they arrived separately, Sam was seen giving Joey a peck on the lips as she sat down to join him.
She was also clutching a brown teddy bear under her arm - perhaps a gift from Joey?
We can't keep up!
