Ashlee Recovering

Ashlee Simpson is reportedly recovering at home with her family after falling ill during a December 15th concert in Japan and a brief hospital stay.

Headliner Simpson had just performed her single “Boyfriend” for MTV Japan’s Cool Christmas concert when she left the stage one-and-a-half songs into her five-song gig. She returned to apologize, adding that she had lost her voice.

She later collapsed and was taken to a nearby hospital for treatment. The cause was said to be exhaustion.

The 21-year-old’s appearance at the December 19th Radio Music Awards in Las Vegas was canceled as a result. “American Idol” contestant Bo Bice was scheduled as a replacement; he, too, then canceled due to complications from intestinal surgery.

The performer has been touring in support of her sophomore album, I Am Me.
