Elton John has lashed out at Madonna on Australian TV show Sunday Night saying "her career is over."

Madonna's onstage antics have been causing a stir on her current MDNA tour and Elton John added his views on the popstar telling Sunday Night: ''She's such a nightmare. Sorry, her career is over. Her tour has been a disaster."

He also spoke about the way she has acted towards Lady Gaga after much talk about how Gaga's work is similar to her own. "If Madonna had any common sense she would have made a record like Ray Of Light and stayed away from the dance stuff and just been a great pop singer and make great pop records, which she does brilliantly. But no, she had to go and prove she looks like a fairground stripper. She's been so horrible to Gaga.''

Madonna recently commented about the similarites between her track Express Yourself and Gaga's Born This Way saying, "She's a very talented artist. I certainly think she references me a lot in her work. And sometimes I think it's amusing and flattering and well done. When I heard [Born This Way] on the radio I said, 'That sounds very familiar'... It felt reductive."
