"Just a few days after checking out of a London-area hospital, pregnant Kate Middleton has fallen ill again with another bout of acute morning sickness -- and although the Duchess does not yet require further hospitalization, husband Prince William has cancelled a Sunday Dec. 9 engagement to be by her side at their Kensington Palace home.\r\n&amp;quot;It is well known that Hyperemesis Gravidarum often recurs,&amp;quot; a St. James Palace spokesman tells Us Weekly, confirming that William has pulled out of his planned appearance at the British Military Tournament in Earls&amp;apos; Court to be with Kate in their Nottingham Cottage residence at the Palace.\r\n\r\n(Known as &amp;quot;HG,&amp;quot; the rare condition affects .03 to 1 percent of pregnant women, and is characterized by severe nausea, vomiting, weight loss, dehydration, lightheadedness and fainting.)\r\nAdds the Palace of the 30-year-old Duchess, who announced her pregnancy on Monday Dec. 3: &amp;quot;Until further notice, to allow the Duchess a degree of privacy during her pregnancy, we do not intend to offer regular condition checks or advise of routine developments.&amp;quot;\r\n\r\nBefore his wife&amp;apos;s second bout, William, 30, donned a tux on Saturday evening to keep a commitment to attend the Winter Whites Gala at London&amp;apos;s Royal Albert Hall, where he commented on his wife&amp;apos;s health woes.\r\n\r\n&amp;quot;I don&amp;apos;t know why they call it morning sickness -- they should call it all day and all night sickness,&amp;quot; the prince joked to former Centrepoint chairman Michael O&amp;apos;Higgins. &amp;quot;[Recovery is] a long old process but she is getting there. She feels like it is going to go on forever.&amp;#x201D;"^^<http://www.w3.org/2001/XMLSchema#string>
