Friends and fans have been offering words of support to singer Kylie Minogue, 37, who has been diagnosed with breast cancer.
Minogue has cancelled her Glastonbury appearance
Minogue has been forced to postpone the Australian leg of her world tour to begin immediate treatment.
Record producer Pete Waterman, who helped launch her pop career, was quick to send his "very best wishes" to her during "this difficult time".
Sir Elton John sent a message of love, wishing Minogue a "speedy recovery".
It was announced on Tuesday that Minogue had been diagnosed with breast cancer, which is in its early stages.
In a positive statement, she said: "Hopefully all will work out fine and I'll be back with you all again soon."
Fans have been flooding the BBC News website with messages of support for the star.
Des Carey of Paris wrote: "Good luck to Kylie and hope she gets well soon, fingers crossed!"
And Paz of London said: "Kylie, you're a fabulous woman and you're a true Aussie battler - you'll beat this, no problem!
"Take heart in knowing how much we all love you and wish you all the very best for a speedy recovery - let's see you flicking those heels on stage again soon, Showgirl!"
Former Neighbours co-star Anne Charleston, who played Madge in the Australian soap, said she sympathised with the singer's plight.
She told GMTV: "When I heard it was like a stab to the heart because it happened to me at that same age.
BREAST CANCER BASICS
Breast cancer is the most common cancer in the UK
One in every nine women in the UK will develop breast cancer at some point in her life
It is the leading cause of death for women aged 34 to 54
Earlier detection and better treatments have improved mortality rates
Physical examination and regular screening can detect a potential problem
"I think she'll come through it fine. She's very healthy generally and I'm sure she will come through it."
Another Neighbours co-star and former boyfriend Jason Donovan said: "I sincerely wish her well with her treatment, Kylie is a strong woman who will fight this battle on every front."
Minogue's pop star sister Dannii said Kylie would take heart from all the messages of support.
She said: "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."
'Hugs and kisses'
Minogue rose to fame in the 1980s as an actress in the popular soap opera Neighbours and later launched a pop career which has spawned 37 hit singles in the UK.
She was due to end her tour as the headline act at the Glastonbury Festival on 26 June, but has cancelled her appearance.
Glastonbury festival co-organiser Emily Eavis said: "It's really sad news for Kylie. Our thoughts are with her and her family at this very difficult time."
She added: "It's much too early to speculate who may replace Kylie in the programme."
In sending his support to Minogue, Pete Waterman said: "I am so shocked to hear this news, particularly since (songwriter) Mike Stock and I had a very poignant reunion with her at her recent Earls Court gig where there were a lot of hugs and kisses.
"My very best wishes go to her, and of course her family, at this difficult time."
Minogue has helped raise money for breast cancer causes over recent years. One of her skimpiest bras was sold at auction for £2,400 three years ago for Breast Cancer Care.
