I don't think any of them would have affairs, it just doesn't seem like them. With Tiana for example, it's more likely Naveen would relapse and have an affair.

Ariel, Poca and Jasmine

Tiana? how?

None of them hopeful. But I can kind of see Ariel doing it too.
Why are people voting for Tiana?

I don't think any of them. I agree with Jessikaroo, I feel that some of the princes would be more likely than the Princesses. I'm not sure why everyone seems to think that Ariel is a whore and would cheat on Eric? ^^

Ariel would never cheat on Eric and technically, considering that the 12 years of trustful relationship and happy marriage is very much a canon if we take the sequel into the account, the very idea of her having an affair with anyone despite being perfectly content and happy with Eric is downright laughable.

Disney Princess couples, the ones that got total endgames at least, are not supposed to having cheating storylines because they are designed to maintain the concept of happily ever after. Pocahontas technically didn't get an endgame with Smith and there was nothing to imply that they ever get back together in the future therefore her relationship with Rolfe later on cannot be considered cheating, especially since she genuinly believed Smith was dead. With that said, after she reunited with Smith she was the one to break the "one princess - one love interest" stereotype so that's why I'm picking her, although there still was no cheating on her part.

None of them really, but I could probably see it with Jasmine the most

Jasmine? The one who was so far up Aladdin's butt despite his lies and the way he treated her? Yeah, no. Jasmine repeatedly runs back to Aladdin (in the sequels too) despite his consistent lying and forgives him almost instantly so I would say Jasmine would be the LEAST likely to cheat.

Well, i'm just focusing this on a different aspect, JUST TO VOTE. I could see her with John Rolfe, but then wanted to be with John Smith (she's already married, in this story) so she was having an affair. Or she was forced to marry some other Native, but she didn't want to divorce J.R...

but of course, none of this will happen.

So...I don't really have a vote.

A revenge affair....maybe to make him jealous or just out of spite....get angry one night at Aladdin and just do it for the heck of it cause she is so pissed off at him, she might regret it later, but she has a tendancy to make stupid, rash decisions with out thinking them through....hell maybe she wouldn't do it unles she was super drunk too(yeah angry and drunk...then I could defiantly see her making a bad decision)

are u people kidding me? jasmine? oh gosh...this is ridiculous..

I don't think any of them would cheat but most likely Rapunzel b/c Flynn is the first man she met and she hasn't had a chance to meet/ get to know other guys IMO
