Kylie Minogue has cancelled her appearance at this year's Glastonbury Festival.

The singer is receiving treatment for breast cancer.

It was announced earlier that the Australian leg of her Showgirl tour has also been cancelled.

According to NME.com spokesperson for the singer said: "Kylie Minogue has had to pull out of her headlining appearance at this year's Glastonbury Festival due to ill health.

"This follows the confirmation early this morning that she has been diagnosed with early breast cancer and that she will undergo immediate treatment. Consequently, her Australian tour, which was due to open in Sydney this Thursday, May 19, will not be able to proceed as planned."

Glastonbury Festival organisers said in a statement: "Glastonbury Festival was saddened to hear the news that Kylie Minogue has been diagnosed with breast cancer...our thoughts are with Kylie at this very difficult time."

Kylie's sister Dannii has also released a statement, she said: "The news is very upsetting. Although as the cancer has been diagnosed at such an early stage we are all very optimistic that everything will be OK. We're all very thankful for the endless messages of love and support Kylie has been receiving - I know all your kind thoughts will mean the world to her as she gets better."
