She SAID she was drunk/hungover,but then that excuse is often trotted out for these things so who knows if it was so.
Considering she claims being in the jungle made her suicidal, I would think she has a tendency to exaggerate & be over dramatic,so the gun stunt fits her attitude.Anything goes when clawing for fame.
So you're suggesting she thought 'I know what'll get me in the papers! I'll dig out a picture that was taken a few months ago - one that'll really offend some people the other side of the Atlantic and post it on Twitter - and at the same time I'll make the whole of the UK hate me'.
She did a truly stupid thing! That is all she is guilty of. Frigging hell - if we executed everyone for doing stupid things - we'd all be dead by now!
