Kate Middleton pregnant: Prince Charles thrilled at Duchess of Cambridge’s pregnancy

Prince Charles today said he was “thrilled” at Kate Middleton’s pregnancy, after the beaming Duchess of Cambridge left hospital following four days of treatment for acute morning sickness.

The Prince of Wales expressed his delight at the “marvelous” news and added: “It’s a very nice thought to become a grandfather in my old age. I’m very glad my daughter-in-law is getting better, thank goodness.”

Prince Charles also alluded to a prank call to the hospital by two Australian DJs on Tuesday morning that duped a nurse into revealing details about Kate Middleton’s health, joking to reporters: “How do you know I’m not a radio station?”

Kate Middleton, 30, was discharged from the King Edward VII Hospital in central London – where she smiled and told reporters she was “feeling much better” – and headed to Kensington Palace to rest.

Kate Middleton, who is less than 12 weeks pregnant, was wrapped up against the cold in a coat and scarf, and the royal couple will now spend time at their London home to allow for her to recuperate.

She was admitted on Monday after developing the condition of hyperemesis gravidarum, and was suffering from the effects of dehydration.

For medical staff to allow Kate Middleton to go home, her severe vomiting must be under control and they are likely to have given her anti-sickness medication.
