I don't see the reason why would they lie. In that case Jassica was lying too when she denied the rumors that she and Tom weren't dating.

The following is my guess, but I did had a strange feeling that Tom wasn't comfortable around EO and she around him before they denied the rumors. Again, all what we saw -their interaction And etc - was in front of cameras, when the backstage reports said they were rather distanced from each other and didn't talk much. I'm talking about TIFF. I'm sure people are watching them like a hawk, and there is always someone sharing what they saw at a premiere, and IF THERE WAS SOMETHING we would know. As usual, we would always know, bed she when there is one person and thousands of eyes, nothing can be hidden.

On the other hand I watched crimson peak today...
