I don't think celebrities owe anyone anything except their best performance, whether it be in sports, movies, music, what have you. If someone wasn't a happy go lucky, outgoing, always smiling person before they became skilled, rich and famous they probably won't change that part of their personality very much after they make it big.

Chilly star personalities


"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 Jungleā€”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.
