Pop star Kylie Minogue has made her first stage appearance since being diagnosed with breast cancer last year.
The singer, 38, came on stage at the end of a gig by her younger sister Dannii at GAY in London's Astoria.
"I have a bone to pick with you," she said, before singing the chorus to Dannii's hit single Jump To The Beat - which she had omitted from her set.
Minogue revealed that she had cancer in May 2005 and underwent surgery in Australia two days later.
She was forced to abandon her Showgirl world tour and an appearance at the Glastonbury Festival after her diagnosis.
The singer finished her chemotherapy in December 2005, but still receives treatment to prevent a return of the cancer.
Last November her tour promoter Michael Gudinski announced Minogue would perform in Australia at the end of 2006.
Glastonbury organiser Michael Eavis has also suggested that Minogue could headline next year's festival.
Breast cancer is the primary cause of cancer death among Australian women, and second only to lung cancer in the US and UK.
