A song by Lady Gaga in which she referred to Princess Diana as "just another dead blonde" has resurfaced, days after the pop star joined Prince William for a Facetime chat to discuss the Heads Together campaign.

In her 2013 track, Princess Die, the 31-year-old refers to the 1997 car crash in Paris in which Diana and boyfriend Dodi Fayed both died.

The lyrics refer to the royal as "just another dead blonde" with the character in the song described as a suicidal woman who took pills after "downing a peroxide shot".

"Wish that I could go in my rich boyfriend's limo/ Right after he proposed with a 16-carat stone wrapped in rose gold," Gaga sings.

She even mentions the trousersuit worn by Diana on the night of her death. "With the paparazzi all swarming around/ In my Louis Vuitton white buttoned down/ So bob your head for another dead blonde/ She just wants to sleep," goes the song.

On its release four years ago, Gaga defended the lyrics. "The People's Princess was mine and my mum's hero when I was growing up," she said.

According to the Mirror, a source claimed: "Lady Gaga was passionate about Princess Diana and, though she admitted it wasn't her best work, she still wanted it on the album.

"But after the adverse reaction it got from fans in the UK when she sang it at her gigs last year, the record company bosses stepped in. They persuaded her to remove it from the album to keep the peace. There still is a lot of emotion."

Lady Gaga opens up to Prince William in support of the #OKtosay campaign

Last week, as part of the royals' Heads Together campaign, the Pokerface singer chatted to Prince William on Facetime about the #Oktosay series of films which encourage people to share their feelings with one another.

Having revealed that she lives with post-traumatic stress disorder, the singer praised Prince Harry for opening up about his struggle to cope with the loss of his mother. He revealed in a candid interview that he was on the brink of a breakdown during his twenties.

In a video Princes William and Harry discussed with Kate Middleton their reluctance to even talk to one another about their mother's death and chose instead to bury the pain.

William pledged to encourage his children to "grow up feeling able to talk about emotions".
