Comedienne Roseanne Barr has launched an online attack on Madonna, accusing the pop star of abusing face-freezing Botox injections.

Both women are followers of the Kabbalah, and were once good friends - but it appears there's no love lost between the two celebrities. In a posting on her blog, Barr ranted, "Please lay off the Botox. You are scaring the children. Act your age. You are doing good things and your face negates your message of spirituality."

According to the National Enquirer Barr has since removed the post.
