Madonna continued her onslaught on Republican vice-presidential nominee Sarah Palin during a show at Madison Square Garden in New York on Saturday night (October 11).

After performing her smash song 'Express Yourself' in front of the sell-out crowd, Madge said “I'd like to express myself to Sarah Palin right now" before she threw condoms into the crowd apparently emblazoned with images of Palin.

The condoms were undoubtedly a swipe at Palin's 17-year-old daughter Bristol who is pregnant. Madonna added that the condoms would promote safe sex as they had a picture of Sarah Palin on them.

Earlier in the night, when Madonna's guitar made a loud screeching sound, she joked: "This is the sound of Sarah Palin thinking."

This episode is just the latest of a string of attacks from Madonna. Last week she told her US fans that Palin was banned from attending any of her shows. She also launched a ditty at the Republican singing: “I'm gonna kick her ass if she don't get off of my street!”

Madonna was also criticised for bracketing an image of presidential hopeful John McCain with Adolf Hitler and Robert Mugabe on the opening night of her world tour.

A spokesperson for Mr McCain's campaign said Madonna's actions were “outrageous, unacceptable and crudely divisive all at the same time.”
