Jamie Lee Curtis has slammed the Oscars and its host Seth McFarlane.

The veteran actress - who has starred in movies such as 'Halloween', 'True Lies' and 'Freaky Friday' - has revealed she was uncomfortable watching the crass humour used by the 'Ted' director during the Academy Awards ceremony last month, taking particular offence to Seth's 'boob song', recounting nude scenes by female actresses on screen.

In a scathing blog posted on The Huffington Post, she said: ''I was offended last week. As an Academy member, as the child of former Academy members and as a woman, I expected more from the best that the movie business has to offer. The Oscars are about honouring art and artists. It is not supposed to be a cheesy vaudeville show.

''The ''boob'' song, as it will be known in perpetuity, may go down as the highest-rated Oscar number in history, but at what cost? I'm sure public executions would get big ratings too, but is that what the Oscars are truly about? Ratings? When did they turn into a 'roast?' ''

The 54-year-old actress continued that audiences wouldn't remember the night's big winners, including Best Actress recipient Jennifer Lawrence, but only the crude skits.

She said: ''I am sorry that this is what we are talking about and not Argo's lovely win or Jennifer's amazing performance or Daniel's eloquence and humour and grace or the fallout from the sequester.

''What we will be talking about is Seth's lack of class and a 14-year-old boy's derogatory word for one of the most beautiful, motherly and literally nurturing parts of the female form.''
