This is an older piece but I don't think it was posted here before.
It is a profile of Paz de la Huerta (Lucy) for New York Magazine by an ex-boyfriend. From the article it appears that Paz may not be acting too much when she plays a free spirited lush with Daddy issues.

"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming

Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
