Ashton Kutcher is not one bit amused by Star Magazine's story that broke today, accusing him of cheating on wife Demi Moore. Ashton took to his Twitter account and it sounds like he's lawyering up.

I think Star magazine calling me a "cheater" qualifies as defamation of character. I hope my lawyer agrees.

STAR magazine - you don't get to stand behind "freedom of the press" when you are writing fiction.

You would think in this age of celebrities suing for false stories that some of these mags like Enquirer and Star would stop printing the more outlandish ones?
