Original Wiggles member Greg Page has collapsed at a bushfire relief concert in Sydney.
The original Yellow Wiggle was taken to hospital after reportedly falling to the ground as he left the stage at Castle Hill RSL on Friday night.
"At the end of the show this evening there was a medical incident off stage involving Greg Page," The Wiggles' official Twitter account said.
"Medics were called immediately and he was taken to hospital where he is receiving treatment. We will provide more information as it comes to hand."
The original Wiggles line-up of Page and Anthony Field, Murray Cook and Jeff Fatt were performing the first of two planned fundraisers for the bushfire relief effort.
Page, 48, left the children's band in 2006 due to poor health and returned briefly in 2012.
He has been diagnosed with orthostatic intolerance, which can cause lightheadedness and fainting.
