She's releasing a new album next week (or the week after) isn't she..........it'll have done her no harm at all that publicity.
She's grown up being a child star and has always been in the public eye. Folk in the press are saying she's going off the rails etc. I reckon it's more than likely that everything is pretty much stage managed, and to be fair she's not doing anything particularly offensive or indeed new. Madonna was doing shit like that 20~25 years ago.
