Jessica Simpson has cancelled a number of promotional appearances after falling sick.
The singer began feeling unwell on Monday (22Nov10) and struggled through a morning appearance on America's The Early Show.
She was unable to perform on the programme as planned, but by the afternoon her health had worsened and Simpson scrapped her bookings for the rest of the day, including an appearance on The Late Show with David Letterman.
Simpson was sent a giant pot of chicken soup by TV host Jimmy Fallon and posted a picture on her Twitter.com page, writing, "Thanks Jimmy Fallon for the massive jar o' chicken soup! Let the healing begin!"
Simpson is scheduled to perform in the MACy's Thanksgiving Day parade in New York City on Thursday (25Nov10). It is not currently known whether she wil be well enough to honour the commitment.
