When Prince Harry makes a commitment, he sticks to it -- even if it means facing the world after a very publicly embarrassing weekend in Las Vegas.

On September 3, two weeks after his boozy party spree in Sin City, the 27-year-old attended the WellChild Awards in London. Wearing a navy blue suit and a red patterned tie, the smiling Brit -- who is a Patron of WellChild -- greeted officers on his way inside InterContinental Hotel.

Harry has yet to make a comment about his wild weekend in the U.S., though party girl Carrie Reichert opened up about it in a recent interview with the U.K. publication The People (as excerpted by The Mirror). In her tell-all, the 32-year-old British beautician who resides in San Diego, California, claimed she and a naked Harry "kissed for 15 to 20 minutes" in his VIP suite.

A Palace insider denies Reichert's claims, telling Us Weekly: "The story is not true. Harry's disappointed, but not surprised, that people are making up stories for money."

While Reichert's version of events may be exaggerated, fellow Vegas partier Melissa Vagner tells the new issue of Us Weekly (out now) that Harry "had two things in his sights: vodka and women."
