Lady Gaga has come under fire for her new song – seemingly inspired by Princess Diana's death.

The Bad Romance star premiered new track – called Princess Die – in Melbourne, Australia, which appear to reference Diana's death in a car accident in Paris in 1997 and makes repeated allusions to a planned suicide.

In the track, Gaga sings: "And wish that I would go / In my rich boyfriend's limo / Right after he proposed / With a 16-carat stone wrapped in rose gold / With the papparazzi all swarming around /So bob head your head for another dead blonde."

Diana was fatally injured in the crash in the Pont de l'Alma tunnel in Paris, while in a car with her lover Dodi Fayed.

The Sun reports that Gaga has previously spoken about her admiration for Diana, saying: "Diana was the most iconic martyr of fame. She died because of it."

The 26-year-old singer's lyrics have been blasted as distasteful, but Gaga told fans that the piano ballad reflected the most "deep and personal thoughts I've ever had".

The singer also says in the song: "I wish that I could cope but I took pills and left a note."

Suicide charities in Australia have slammed the singer's words and are worried about the message she is sending to impressionable fans.

Chris Wagner, communications director for Lifeline, said: "We understand artistic license and we get artistic expression, but celebrities need to recognise that they're role models for young people in the community."

"Young people often live and breathe by the lyrics to the songs of their favourite stars," he said.

Princess Die "may or may not" be on Gaga's next album, the star said.
