LONDON (TheBlaze/AP) — If you've noticed that the Duchess of Cambridge, wife of Prince William, has been out of the lime light within the last month, it's because she's being treated for severe morning sickness accompanying her second pregnancy, which was formally announced Monday.
The couple's Clarence House office said they and their families were "delighted" with the new baby news.

The former Kate Middleton was being treated at Kensington Palace for severe morning sickness, Clarence House said.
She was hospitalized for the same condition, hyperemesis gravidarum, during her first pregnancy with Prince George, who was born in July 2013.

The illness means the 32-year-old duchess may need extra hydration, medication and nutrients.
