LONDON (CNN) — Catherine, the Duchess of Cambridge, left the hospital Thursday morning after being admitted for acute morning sickness from her pregnancy.

She emerged from the hospital accompanied by her husband, Prince William, and was driven away by a waiting car.

“The Duchess of Cambridge has been discharged from the King Edward VII Hospital and will now head to Kensington Palace for a period of rest,” said a St. James’s Palace spokesman.

The future royal parents thanked those at the hospital for their care and attentiveness.

News of her pregnancy was announced Monday when the former Kate Middleton was admitted to King Edward VII Hospital. She was diagnosed with hyperemesis gravidarum, a condition that involves nausea and vomiting more severe than the typical morning sickness.

Her discharge from the hospital comes a day after two Australian DJs hit the headlines in international media for a prank call they made to her nurse.

2Day FM apologized Wednesday for a prank it said was “done with light-hearted intentions.”

The duchess is not yet 12 weeks pregnant. The palace is not announcing a due date for the child.

The child will be next in line to the British throne after William, regardless of whether it is a boy or a girl.

Planned changes to the law of succession that end the tradition of a boy jumping over an elder sister are already de facto in effect, the British Cabinet Office said.
