Screwed up celebrities with normal parents?

OK, I've hit a bit of a roadblock, so I figured I'd turn to my go-to folks on SportsJournalists.com for help.
I'm working on a mini-project for school, and I'm trying to come up with an example (or two) of a well-known celebrity (probably redundant there) screw-up who comes from a relatively stable, solid upbringing. The more messed up the individual, and the more stable his/her home life growing up, the better.

If anyone can think of any examples, I'd appreciate it.

 

I don't think Charlie Sheen came from a dysfunctional home. His parents have been married for 50 years and his siblings all seem fairly normal.

 

That was my first thought exactly!

 

That's helpful. The best I had come up with so far was Amy Winehouse, but I don't know how relevant she is anymore.

 

Celebrities are relevant?

 

I recall reading some gossip items that said her dad was a little nutty.

 

William Burroughs

 

Two examples of now-sane celebs who came from very fucked up parents: Drew Barrymore and Jennifer Aniston.

 

Yeah, as I was thinking about it, crazy-to-normal seemed to be easier to find. FWIW, I decided to go with the Sheen/Estevez clan. I appreciate the input.

 

Katie Holmes.

 

It's an interesting request, because for the most part, the only celebs' parents who we're familiar with are one who have parents who are celebrities or are so famous that we know the backstory of their parents.
