Prince Harry's secret nickname for Pippa Middleton has sparked speculation that Kate's little sister didn't wear any knickers under her slinky ivory dress at the Royal Wedding.
With no visible panty line, Her Royal Hotness's male fans got themselves into a frenzy about exactly what underwear - if any - she had on.
Maybe Prince Harry knows the answer - he calls Pippa 'Commando'.
'She thinks he's got a really cheeky sense of humour,' a source tells The Sun.
Pippa refers to Harry as 'Captain' because of his Army rank and the pair have always got on well.
Harry, 26, and Pippa, 27, had afternoon tea at The Troubadour pub in Chelsea recently and there was a real spark between them at Kate Middleton and Prince William's wedding in April.
Pippa's still believed to be dating city financer Alex Loudon but Harry's on-off relationship with Chelsy Davy is up in the air.
