Kate Middleton is Pregnant; Hospitalized

Nearly 20 months after their wedding, Prince William and his wife Kate Middleton—the Duchess of Cambridge—are expecting their first child. Kate has been hospitalized with hyperemesis gravidarum, a severe morning sickness.

The baby, due next year, will be third in the line to the throne, now that Britain's antique rules of royal succession have been changed to allow a first-born girl to succeed even if she has younger brothers.

USA President Obama and first lady Michelle Obama weighed in, congratulating the couple on "the welcome news" through spokesman Jay Carney in Washington.
