The Duke and Duchess of Cambridge -- a.k.a Prince William and Kate Middleton -- are "expecting a baby  in July," according to a royal announcement  and the news has folks wondering  if the wording means the end of the rumor that she's carrying twins.  We think it means this: That royal baby will be a girl .
Ever since Kate was hospitalized  following severe morning sickness , rumors have been swirling that she is pregnant with twins . That's because severe morning sickness (hyperemesis gravidarumis) is more common in women carrying multiple babies, according to the American Congress of Obstetricians and Gynecologists . It's thought that spiking hormone levels are to blame.
What do you think of this theory? Does more morning sickness = baby is a girl?
