Irish singer Brian Mcfadden axed a planned appearance on a reality TV show on Sunday after falling sick.
The former Westlife star was due to film a slot as a panellist on I'm A Celebrity... Get Me Out of Here Now!, a spin-off of the jungle-based survival show.
He was taken ill after travelling to the programme's location on Australia's Gold Coast and had to pull his appearance at the last minute.
McFadden has since been stocking up on medication and hopes to be well enough to film his segment on Tuesday instead.
In a post on Twitter.com, he writes, "Being sick sucks!!!!!... Hoping I'll be better in the morning so I can go into the jungle for I'm a Celebrity Get Me Out Of Here. Full of tablets and injection."
