R&B star R. Kelly is battling the flu on the road.
The I Believe I Can Fly hitmaker is currently touring North America with singer Keyshia Cole, and he insists the show must go on even though he feels terrible.
He has been guzzling flu medication in a bid to overcome the illness, but fears he won't be on top form when he takes the stage in Louisville, Kentucky on Wednesday night (13Jul11).
In a post on Twitter.com, he writes, "I refuse to take another cup of theraflu (medication)! I feel like my throat is coming back. I've been in bed sweating like crazy."
