Madonna has banned the Republican vice-presidential candidate Sarah Palin from attending any of her concerts.

The singer told a crowd in Meadowlands, New Jersey on Saturday (October 4th) that the Alaskan governor wasn't allowed to her “party”.

“Sarah Palin can't come to my show. It's nothing personal,” Madonna was quoted by the NY Post as saying, before adding: “Here's the sound of Sarah Palin's husband's snowmobile when it won't start.”

It's not the first time Madonna has spoken out against the Republican party during her 27-date Sticky & Sweet world tour.

The singer was criticised for bracketing an image of presidential hopeful John McCain with Adolf Hitler 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.”
