NEW YORK – Singer Ashlee Simpson has been hospitalized after collapsing Thursday night following a performance in Tokyo.
Us Weekly reports that Simpson had just performed her single "Boyfriend" for MTV in Japan when she told the audience she felt sick. She then collapsed in an elevator and was rushed by ambulance to a hospital.
Her representative confirms the report, but isn't providing information about her condition.
Simpson is the younger sister of Jessica Simpson. She has been touring following the release of her second album, "I Am Me."
Her scheduled appearance Monday at the Radio Music Awards has been canceled.
