The loss of innocence is a big thing in the life, marking the point when they stop being a child and truly become an adult.

When it comes to the world of celebrities, however, this distinction is harder to make. Thank golly gosh for the Olsens then, who we’ve been able to watch all their lives as they became adults! With problems!

The latest occurrence in Mary-Kate Olsen’s quest for womanhood has come as she seeks immunity from prosecution in the investigation into Heath Ledger’s death earlier this year. Oh how she’s grown!

Investigators looking at the cause of Ledger’s death want to ask Mary-Kate some questions about a couple of powerful painkillers the Dark Knight star had taken before his death. However, the once cherub-faced little angel has now turned into a character akin to a mob boss, it would appear, as her lawyer has told the feds she won’t cooperate without immunity.

Aww, isn’t that sweet?

We’ve seen Mary-Kate on her journey through being a twin-child star, through growing up very much in the public eye and then taking on the necessary change from child to adult actress that brings down so many young actors.

Then we got to see her vilified by PETA, move away from solely working with her sister, having kidney problems and dealing with anorexia.

But this time she’s really gone and grown up – requesting legal immunity from federal investigators. It’s a big step in the life of any young woman and one that is sure to cement her position as a proper, bona-fide grown-up.

In a statement released to the media, Mary-Kate Olsen’s lawyer said:

“Despite tabloid speculation, Mary-Kate Olsen had nothing whatsoever to do with the drugs found in Heath Ledger’s home or his body, and she does not know where he obtained them.”

Which is all well and good, we’re not going to argue with that, nor are we going to accuse anyone of anything. But it does seem a bit strange when someone refuses to speak to investigators unless they are guaranteed immunity from prosecution. The statement goes on:

“Regarding the Government’s investigation, at Ms. Olsen’s request, we have provided the Government with relevant information including facts in the chronology of events surrounding Mr. Ledger’s death and the fact that Ms. Olsen does not know the source of the drugs Mr. Ledger consumed.

We don’t know the source of the information being quoted in the media regarding the Government’s inquiry, but these descriptions are incomplete and inaccurate.”

On the other hand though, while it may look like the Olsen that isn’t Ashley has something to hide, she may well be asking for these stipulations just to be on the safe side. It’s understandable, really, if she was involved with Heath Ledger just before his death – either as ‘just friends’ or more – that she’d want to play things with more caution.

Regardless, hecklerspray will be keeping a close eye. And we don’t grant immunity.
