Opinion: "In the world of IT girls"

Every teenage girl obsessed with celebrities, who is wearing what, who is making up, breaking up understands me when i say "What is going on with young hollywood?!"
In the past month:
-Lindsay left rehab after an extended stay, sold her 21st birthday party to OK! and then gets arrested for DUI and posession of cocaine which was found in her pants and she claims "She borrowed the pants."
-Nicole has been sentenced to four days jail for her incident which included driving on the wrong side of the highway, smoking pot and under the influence of vicodin. Then to try and save her image she did an interview with Dianne Sawyer and told the world what we already knew - she is pregnant!
- Paris after leaving jail for her driving without a licence charge she promised to change her ways. Only days later do we find Miss Hilton frolicking on a beach and going to party after party
And i dont think she is an IT girl but how could I not mention Britney Spears.
This girl has fallen from grace, more than the others. In a space of less then a year she has flashed herself several times,has been seen partying all hours, shaved her head, went into rehab,publicly fought with family members including her ever present mum and got a divorce! (and we thought Kevin Federline was the bad half in that relationship!
With her crazy behaviour on a recent magazine shoot with OK! you can see Spears is not all there and I am worried she will be the next superstar to be found dead in a 5 star hotel.
All these girls have built multi-million dollar empires based on their image. Rachel Zoe, stylist to the stars helped Nicole get on the best dressed lists and I fel in love with Nicole for her style.
Lindsay has a true talent for acting. Not many child stars make the transition over to adult acting so successfully. I loved Lindsays latest release in Australia, Georgia Rule.
I don't believe the jail stint has affected Paris Hilton's popularity. If anything it has made her even more popular.
But when is enough, enough? Who has the power to control these "IT" girls?
I believe its up to their management, family and friends. These girls need boundaries, not people surrounding them saying "yes" all the time.
