Maybe so, but if that’s the case, then why did she delete the “bottle of wine for the train home” post then Why delete unless you’ve got something to hide?Not to be that person, but how do you know they didn't get a taxi home and will pick his car up from the train station today? Quite a common thing to do... I personally think it's a bit extreme emailing her management with no evidence.
The previous time when she was photographing the AU vodka and glasses of wine all night then driving home, fair enough, but this time seems like a bit of a reach.
