If you had a really, really awful looking film coming out and you're clearly too old to pretend to be pregnant like Eva Longoria, what do you do?

Easy, if you're Diane Keaton you swear like a titting docker at the most inappropriate time you can think of, that's what. On a live visit to Good Morning America to promote her Mad Money film yesterday, Diane Keaton decided to screech "If I had lips like yours I wouldn't have to work on my fucking personality!" at host Diane Sawyer like some sort of pottymouthed harpy.

Yes, we've got video.

Thanks to her chronic inability to hang out at rehab or go through protracted custody battles with her redneck husband or flash her 62-year-old ladyparts for the paparazzi as she gets out of cars, Diane Keaton has so far managed to escape the attention of hecklerspray. And that's the way it was going to stay, until Diane Keaton decided to go on breakfast TV and start swearing like a drunken taxi driver, at least.

But then that's what Diane Keaton went and did. Promoting her rubbish-looking new film Mad Money – which loses points for being based on a not-very-good British drama called Hot Money and then loses subsequent points for having the word 'Mad' in the title and co-starring Katie Holmes - on Good Morning America, Diane Keaton decided that the best way to get the movie out there would be to scream "fucking" during a conversation about the host's mouth. Look…

See, people? This is the real cost of the writers' strike. If stars aren't allowed to go on the big talkshows like Leno to promote their films, they're going to have to get inventive. Just this week we've seen Paris Hilton possibly become Harvard's woman of the year because of The Hottie And The Nottie, we've seen Eva Longoria invent a non-pregnancy because of Over Her Dead Body and now Diane Keaton is shouting the word 'fucking' on breakfast television like some sort of wrinkly Sex Pistol.

Where will this all end? Will Raven Simone kick a tramp in the nutsack before College Road Trip comes out? Will Kate Hudson anally violate someone with her fingers while screaming fascist propaganda in their ear to mark the release of Fool's Gold? Writers, come back, we just want this blasted strike over.
