Following the announcement on Monday (3rd December) that Kate was expecting her first child with hubby Prince William, she was admitted to the King Edward VII hospital in London to seek treatment for Hyperemesis Gravidarum.
So far, only Wills has been spotted visiting the Duchess of Cambridge, with the Duke seen at the hospital every day since she was taken ill.
P-Middy and James were snapped leaving the hospital yesterday, with Pippa wearing a beige belted trench coat - hiding her famous bottom - and completing her look with knee-high tan boots.
Pippa's visit comes after it was alleged that she stands a good chance of being named as a godparent for Kate and Wills bundle of joy, with Prince Harry also expected to be given the role.
Joe Little, managing editor of the Majesty royal magazine, told the MailOnline: “I think Harry and Pippa are very likely. As you know most people have just one or two godparents. But in royal circles you have a lot more, certainly William had quite a team."
“I rather think they won't have quite so many - perhaps four. Harry would take care of the royal connection and Pippa would take care of the Middleton side. There are few options amongst their close friends. The van Cutsems and the van Straubenzees certainly."
The Royal expert continued: "William is a godfather of several children, one of whom was Grace van Custem, the little bridesmaid covering her ears on the balcony on their wedding day. Quite possibly the favour will be returned to them.
"I would say Harry and Pippa, a Van Cutsem, and maybe one of Kate's close chums from school and that might be it. Whoever it is it would have been given careful consideration. It would be a huge honour to be the godparent of a future King or Queen.”
In other K-Middy news, two Australian radio DJs who pranked the King Edward VII hospital by pretending to be the Queen and Prince Charles in order to talk to Kate have apologised for their actions.
Mel Greig and Michael Christian stated: "We were very surprised that our call was put through. We thought we'd be hung up on as soon as they heard our terrible accents.
"We're very sorry if we've caused any issues and we're glad to hear that Kate is doing well."
A spokeswoman for the radio station said: "2Day FM sincerely apologises for any inconvenience caused by the inquiries to Kate's hospital.
"The radio segment was done with lighthearted intentions. We wish Kate and her family all the best and we're glad to hear she's doing well."
