Video: Rihanna Sick of Touring?

Rihanna was performing “Umbrella” with Chris Brown at a show in Sydney, Australia on Friday when she abruptly walked off the stage holding her stomach. However, despite rumors, the 20-year-old singer is doing just fine.

“It was very hot at the venue, so after Rihanna’s set was over, she went off stage to sit down, catch her breath and have some water. She is perfectly healthy and will be at her show tomorrow,” a rep for Rihanna tells E! Online.
