No wedding nerves for Prince Harry, says Royal photographer

Prince Harry and Meghan Markle arrived in Windsor earlier this week in preparation for their May 19 nuptials. 

And while the couple were all smiles, the lead-up to their wedding has been anything but relaxing - especially with the added family dramas with the actress's father and half-sister.

But The Sun's Royal Photographer Arthur Edwards - who's watched the now 33-year-old Prince grow up through the lens - says he'll be his cool, calm and collected self on the big day.

"No, no, he's not nervous - he'll be on the front foot the whole way," Edwards tells 9Honey outside Buckingham Palace.

"He's going to be pretty cool. This guy's served in two armed conflicts, served two terms in a war zone and he's a pretty tough guy, but he's going to be thinking like every bride and groom does... it's probably the biggest decision you make in your life.

"He comes from a broken home, so he obviously doesn't want that to happen to him. So does [Meghan] and she doesn't want that, so they're going to have to work pretty hard at it but I think they've talked it through."

So, will their public displays of affection continue at the Royal Wedding? Edwards seems to think so.

Although, he's not too sure if we'll see the couple's first kiss on the West Steps or during the carriage procession.

"Certainly if I was there [near the West Steps] I'd ask for it," he laughed, recalling asking Prince Charles to kiss Camilla on those very steps in 2005, but getting a cheeky 'no' from the Prince of Wales.
