But the 33-year-old managed to laugh off questions about inviting his pal Barack Obama to his upcoming nuptials, having interviewed the former US President for a segment on the radio show.
"One of the dangers of the internet is that people can have entirely different realities". "It was fantastic", he admitted, while editing the December 27 edition of BBC Radio 4 Today.
The prince asked the former president plenty of questions ranging from work to his personal choices.
Obama said it was important for people to get offline and meet others in their communities, "because the truth is that on the internet everything is simplified and when you meet people face to face it turns out they are complicated", he said.
"I think it was a satisfying feeling that was mixed with all the work that was still undone, concerns about how the country moves forward, but you know, overall there was serenity there", Obama said.
Barack Obama has been out of office for almost a year, but the 44th president is still answering tough questions, this time courtesy of Prince Harry.
While the guest list is yet to be finalised for the much anticipated royal wedding, the young prince is reportedly intending to invite the former president and former first lady Michelle Obama who are personal friends of the prince.
St George's Chapel was most recently the scene of the wedding of Peter Phillips - son of Princess Anne and cousin to Harry - who married Canada-born Autumn Kelly there in 2008.

"It was that grassroots army that really fuelled my campaign - in part brought together by the new technologies of the time of social media", he said.
"It was just a really lucky shot that captures the moment", says amateur photographer Karen Murdoch.
Prince Harry also has a history of controversial action, including his 2005 appearance at a fancy dress party wearing a Nazi Uniform, complete with swastika.
Barack Obama also said that he doesn't have a New Years resolution as he doesn't believe in them: "People typically tend to break them".
