Rihanna ‘Perfectly Healthy’ After Apparently Collapsing Onstage During Duet With Chris Brown

Singer was performing 'Umbrella' when she abruptly left stage, holding her stomach.

A rep for Rihanna said the singer is “perfectly healthy” after nearly collapsing onstage during a concert Thursday at the Acer Arena in Sydney, Australia.

In videos posted online, the 20-year-old singer, clad in a corset, hunches over and holds her stomach while performing her hit “Umbrella” with tourmate Chris Brown . While some reports claim she finished her verse before running offstage, where paramedics reportedly were waiting for her, the video shows the music — and Brown — continuing after she exits the stage.

“It was very hot at the venue, so after Rihanna’s set was over, she went offstage and needed to sit down, catch her breath and have some water,” a rep for the singer told MTV News on Friday (November 7). “She is perfectly healthy and will be at her show tomorrow.”

TMZ reported that Rihanna may have felt ill due to a problem with the venue’s air-conditioning system, and Radar reported that she sought medical treatment at a local hospital.

According to her rep, the singer is expected to resume the tour with Brown as scheduled Saturday night in Sydney. The duo have been on tour in Australia and New Zealand since late last month; the last show is scheduled for November 11 in Perth.

Rihanna was recently named the face of Gucci’s UNICEF campaign. Gucci’s Frida Giannini described Rihanna as having a “strong personality” and said that she will work well for the campaign because “a musician and a beautiful woman was the perfect icon for this campaign.”
