Britain's Prince Harry will be a "mischievous" uncle, says a family friend.
The 28-year-old royal was thrilled to discover his older brother Prince William is expecting his first child with his wife Catherine. Sources close to Harry believe he will have an enormous amount of fun after his niece or nephew is welcomed into the world next year.
"He will be a wonderful uncle - [think of] the mischief he will want to get up to with the [children]!" a source told People. "I can see it already."
Harry is currently on a tour of Afghanistan, serving as an Apache attack helicopter pilot. He has only been able to speak to William via email and phone calls and is expected to remain in Afghanistan until early next year.
Harry also sent Catherine a touching get-well message after she was hospitalised with severe morning sickness.
The Duchess of Cambridge spent a few days at King Edward VII hospital in London last week and is believed to have suffered another attack of sickness over the weekend.
The duchess has been diagnosed with Hyperemesis gravidarum, which causes severe nausea and vomiting and can lead to dehydration and weight loss.
Her stay at the medical facility was thrown into turmoil after an Australian radio station hoaxed staff into sharing details about Catherine's condition.
On Friday Jacintha Saldanha was found dead in staff accommodation near the hospital, after allegedly taking her own life. She was one of two nurses duped into believing that 2Day FM hosts Mel Greig and Michael Christian were Queen Elizabeth II and Prince Charles.
The presenters have now given a series of interviews in Australia about the prank, where they have said they are "incredibly sorry" for the events.
"I remember my first question was, 'Was she a mother?' I am very sorry and saddened for the family. I can't imagine what they are going through... I am just so devastated for them," Mel said. "I am really feeling for them. It was never meant to go that far. This wasn't meant to happen."
Michael has said he is "shattered, gutted and heartbroken".
"No harm was intended on Jacintha or the other nurse or Kate or Prince William or anyone," he said. "It was an incredibly tragic turn of events that no one could have predicted and for the part that we have played we are incredibly sorry."
The radio station is facing an inquiry by the Australian media watchdog following the broadcast.
The radio station's owner Southern Cross Austereo Media said it has suspended advertising on 2Day FM, terminated Mel and Michael's radio show and suspended all prank calls.
In a statement the company also said it had attempted to contact the hospital before the hoax was broadcast.
