Prince Charles is thrilled by the prospect of becoming a grandfather.
The future king commented for the first time yesterday about this week's news that his daughter-in-law is pregnant.
"I'm thrilled, marvellous. It's a very nice thought to become a grandfather in my old age, if I can say so," Charles, 64, told reporters in London.
Earlier on Thursday, Catherine, 30, was discharged from an exclusive London hospital where she had spent three nights being treated for acute morning sickness.
"I'm very glad my daughter-in-law is getting better, thank goodness," Charles said.
During Catherine's stay, two Australian radio announcers made a prank call to the hospital pretending to be the Queen and Prince Charles.
The 2Day FM jocks were provided with private details of the duchess's condition by a nurse who referred to DJ Michelle Grieg as "ma'am".
In response to the hoax call, Charles at first answered reporters questions with: "How do you know I'm not a radio station?"
The broadcaster has since apologised for the prank, while the hospital considers legal action.
Catherine is now resting at her London home, Kensington Palace.
