Lebanese singer Elissa collapsed on stage on Friday night during a performance at Dubai's Global Village.
It is not apparent why the 46-year-old star passed out on stage, and there has been no official statement from her management, but a video posted by a fan shows members of her band carrying her from the stage.

Elissa, a previous judge on The X Factor Arabia, has sold more than 30 million albums, and in 2005, 2006, and 2010 received the World Music Award for Best Selling Middle Eastern Artist. She is also the most popular Arab singer on Twitter, with a following of over 13 million.
