Prince Harry of Wales will be returning to the U.S. on May 7 to accept the Atlantic Council's 2012 Award for Distinguished Humanitarian Leadership in Washington, D.C., on behalf of his joint charity work with brother Prince William.

Prince Harry, brother to Prince William and son to the late Princess Diana, made headlines during his last visit to the states due to a reported short tryst he had with a San Diego cocktail waitress while English troops were stationed in Southern Calif. in Oct. 2011.

When People magazine questioned the St. James Palace about the 27-year-old royal's U.S. arrival, his representatives stressed that Harry is receiving the award on behalf of "his brother the Duke of Cambridge, and their joint work through the Foundation of Prince William and Prince Harry." The award recognizes their charity's service to war veterans and members of the armed forces.

A spokeswoman from Buckingham Palace told CNN that Harry's U.S. trip was expected to be very short, perhaps less than 24 hours.

According to CNN, Harry will attend the ceremonial dinner at the Atlantic Council, as well as meet and greet athletes from the Warrior Games, a Paralympic athletic competition for members of the armed forces, held in Colorado.

Prince Harry has been involved with such charitable organizations as Walking With the Wounded and Help for Heroes, according to People magazine.

CNN predicts that like his royal brother and sister-in-law, Kate Middleton, Prince Harry's visit will gain a lot of media attention, no matter how short it is.

On the day of Harry's ceremony, Prince William and Kate Middleton will be presenting prizes at the Badminton Horse Trials, according to People magazine.

The Atlantic Council is a non-partisan, Washington D.C.-based think tank that promotes constructive U.S. leadership abroad.
