Britney Spears Was The Inspiration For Gwyneth's Character In Country Strong

Inneresting!
According to the writer and director of Country Strong, Shana Feste, Britney Spears was her inspiration when writing for the character, played by Gwyneth Paltrow.
In the movie, Gwyneth plays a country singer who's a strugglng addict. Feste said when writing for the character, she used Britney's public meltdown as inspiration to show how the media lifts bright, young, talented stars only to bring them down and destroy them.
Feste continued:

"That's where this movie came from. I mean, I was seeing what was happening in the media to Britney Spears. I finished the script when Michael Jackson passed away. I think it's tragic how we treat people who give us so much, and we love to see them knocked down to build them back up again, to knock them down again. It's a weird fascination."

We wonder if Gwyneth used the same inspiration when preparing for the role.
Do U see any comparison between the two?
