I don't know, it doesn't seem to me that Nikki is 'drunk and incapable' as the various captions allege, and in most of them she doesn't, to my mind, look particularly upset, indeed there are a few where she appears to be grinning quite happily.
I suspect, however, that the two lads with whom she seems to be larking about took things a little too far by picking her up and flashing her a*se to the paps. When you are as tiny as she is, it must be a real hazard as every burly 'jack the lad' reckons it'd be a laugh to give you a firemans lift.
When she's squatting in the back of the cab with her coat on her knees and her hands inm her hair she's clearly annoyed (perhaps because she's lost something?), but in general it just looks like overly boisterous drunken behaviour rather than Nikki being helpless and exploited as some have suggested in another thread.
Nikki may be a miniscule little pixie who cannot hold her drink, but I personally believe she's a much tougher cookie than many give her credit. She may be a bit embarrassed and annoyed this morning, but I suspect she will also allow herself a little laugh at some of these pictures.
