Ringo Starr and Ron Wood have also paid their respects

Paul McCartney, Mick Jagger, Ringo Starr, Ron Wood and Elton John are among the artists who have paid tribute to Prince, who died yesterday [April 21], aged 57.

Aretha Franklin called him a “a one-of-a-kind”.

Franklin said that Prince’s death was “such a blow. It’s really surreal. It’s just kind of unbelievable,” in an interview on MSNBC which you can watch below.

She went on to describe Prince as “a very, very unique musical individual who was so into his music – he was music to the max.

“I think that he was a very explorative and as I said he was one of those artists that go into the studio and stayed in the studio – he would sleep in the studio.”

“Myself when I finish recording as an artist I go home and I am through with it until it’s time for me to go back in the studio but some artists just stay in the studio because they love music like that,” she continued.

Meanwhile, NASA Tweeted a photograph of a purple nebula, to mark Prince’s death.

Elton John posted a photo on Instagram, calling Prince “a true genius. Musically way ahead of any of us.”

The cause of Prince’s death has yet to be established, although an autopsy is due to be carried out later today [April 22].
