Clarence House has refused to comment on newspaper reports claiming Prince Harry went to a lap dancing club.
Harry has been called the "party Prince"
The Daily Mirror and the Sun say the 21-year-old and his friends visited the Spearmint Rhino club near Slough, to celebrate the end of his army training.
Former Royal press secretary, Dickie Arbiter said it would not matter "one hoot" if the prince had been there.
"He's let his hair down, and so what? So many thousands of other people do exactly the same thing," he said.
"He's a 21-year-old, he's just finished 12 months at Sandhurst which is pretty gruelling for anybody and he's doing what thousands of youngsters do when they graduate, whether it's from Sandhurst or whether it's from university," he added.
Both newspapers say the prince declined the offer of a lap dance in the club, in Colnbrook, Berkshire.
Novelist and friend of Prince Charles and the Duchess of Cornwall, Jilly Cooper, told Five Live anyone shocked by the prince's actions was "really very prudish".
"I mean he had a lovely time. He obviously got on with his mates. He passed out in very gruelling circumstances - he may well have to go to Iraq.
"He's under a lot of pressure. And then he goes out and has a jolly evening. I can't see anything wrong with it at all."
Prince Harry leaves Sandhurst next week, and will be watched by the Queen and the Duke of Edinburgh, the Prince of Wales and Duchess of Cornwall and his brother Prince William as he marches in the traditional passing out parade and commissions as an officer.
He will join the Household Cavalry's Blues and Royals regiment.
The Household Cavalry recently had squadrons on operational duty with the UN and Nato in Bosnia and Kosovo, and is expected to return to Iraq.
