Sir Elton John has continued his long running feud with Madonna by labelling her a “fucking fairground stripper” whose “career is over”. He criticised Madonna’s treatment of Lady Gaga.

Madonna recently hit out at Lady Gaga’s ‘Born This Way’, which has often been compared to her own ‘Express Yourself’ saying: “I thought, ‘What a wonderful way to redo my song.’ I mean, I recognised the chord changes. I thought it was… interesting.”

Sir Elton, who had previously described ‘Born This Way’ as “the new gay anthem” said that Madonna had no authority to criticised others in the industry. The star told Australian TV: “Why is she such a nightmare? Sorry, her career is over. Her tour has been a disaster and it couldn’t happen to a bigger c*nt.”

He continued: “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 fucking fairground stripper. She’s been horrible to Gaga.”

Sir Elton’s civil partner David Furnish criticised the decision to award Madonna Best Original Song at the Golden Globes for ‘Masterpiece’ taken from her directing debut ‘W.E.’ Furnish tweeted: “Madonna. Best song???? F*** off!!!” later writing: “Madonna winning Best Original Song truly shows how these awards have nothing to do with merit.

“Her acceptance speech was embarrassing in its narcissism. And her criticism of Gaga shows how desperate she really is.”

Lady Gaga’s single Born This Way was hailed as ”the new gay anthem” by Sir Elton and features lyrics including: “No matter gay, straight, or bi/ Lesbian, transgendered life/ I’m on the right track, baby” and “Don’t be a drag, just be a queen.”

Lady Gaga announced the launch of the Born This Way Foundation last November to tackle bullying.

In a statement at the time Lady Gaga said: “My mother and I have initiated a passion project. We call it the Born This Way Foundation. Together we hope to establish a standard of Bravery and Kindness, as well as a community worldwide that protects and nurtures others in the face of bullying and abandonment.” She added that the foundation will work towards “youth empowerment and equality by addressing issues like self-confidence, well-being, anti-bullying, mentoring and career development and will utilise digital mobilisation as one of the means to create positive change.”

Gaga has long been a campaigner against bullying. In September she met with US president Barack Obama to talk about the issue of bullying.

The meeting came after a gay teenager, Jamey Rodemeyer killed himself after being bullied. He had previously recorded an ‘It Gets Better’ video and shortly before killing himself posted a line from a Lady Gaga song on his Facebook wall: “Don’t forget me when I come crying to heaven’s door.”

Paying tribute to the teenager, Gaga told the audience at the iHeartRadio Music Festival in Las Vegas: “I just wanted to take a moment because we lost a little monster this week. Jamey, I know you’re looking down on us and you’re not a victim, you’re a lesson to all of us.”
