There was an episode on Towie where I think Chloe Sims and Danni spoke to Georgia about Tommy rumours and she was quite calm then sent Tommy a message or called him to meet her. He then goes to Georgia's parents house and waits for her and looks shit scared!!
He denies is and Georgia again, seems quite calm and agrees with him about she knows its just a rumour.
He looked too nervous to me for it to be a rumour and I'd say he probably did cheat on her then.
Wouldn't be surprised if he did and she knew and they both kept quiet as they were desperate to be the "Essex power couple"
When they first got together, here are episodes where she gives him rules while they are away and he definitely comes across like he would have been seeing more than one girl at the same time.
She does seem to have "tamed" him though
Oh I forgot about that allegation too!!!
Georgia always comes across that with all the allegations, that she knew about them and knew they were rumours
