Pop Singer Ashlee Simpson collapsed off-stage yesterday in Tokyo following an MTV Japan performance, and is currently recuperating in a Japanese hospital.
A Simpson publicist has confirmed to TMZ that she did collapse, but that she's recovering well and should be fine. Sources tell TMZ that she was suffering from "exhaustion".
Working hard to dispell rumors that she's more than a lip-syncing performer (following last spring's SNL fiasco), Simpson had reportedly just performed her single "Boyfriend" from her new album, "I Am Me," when she told the crowd that she was not feeling well, and left the stage.
Simpson's appearance on Monday's Radio Music Awards in Las Vegas has been cancelled.
