Prince Harry's friends have been warned to be "extra careful" about what they post on Facebook.
In the wake of nude photos of the British prince being published on the web and newspapers, royal aides have warned friends who were at his wild Las Vegas party on Friday (17.08.12) to be careful about what they post on social media sites.
A royal source told the Daily Mirror newspaper: "Harry's circle of close friends are usually extremely discreet but throughout this trip they seem to have let their guard down.
"Sensitive information has been posted on Facebook. They think it's all a bit of a laugh but seem to have forgotten they are friends with the queen's grandson and have been warned to be extra careful."
The pictures of the naked prince were taken on a mobile phone after he initiated a game of strip billiards after he and friends, including Tom Inskip and Arthur Landon, invited a group of women back to their £4,750 per night suite at the Wynn hotel in Las Vegas.
Meanwhile Harry's father, Prince Charles, is said to be particularly upset with his actions and ordered him to lie low now he's returned to the UK.
A source said: "Charles is not impressed with Harry's antics and thinks he should have known better.
"He has advised his youngest son to lie low and not be seen falling out of any nightclubs.
"He gave him a talking to as any protective father would because he wants to make sure this kind of thing doesn't happen again.
"But he wasn't too unkind. Harry is embarrassed enough as it is."
