Kylie Minogue was expected to perform at one of Elton John's fundraisers on Thursday night, but evidently Kylie called in sick!

After winning her battle with breast cancer, sources close to Kylie say she isn't taking any chances and found herself too tired to perform at the fundraiser.

Instead, Elton took the stage himself.

"Elton doesn't usually perform at his own parties but he wasn't upset," a source told the Sun.

Elle Macpherson, Naomi Campbell, Hugh Grant and Boris Becker were among the guests Elton's home in Windsor, Berks.
