Since then, however, the notoriously fun-loving prince has kept an uncharacteristically low profile, declining to speak to photographers as he returned home to England and notably absent from the Paralympic Games in London Thursday attended by his brother and sister-in-law, Prince William and Kate Middleton.
British tabloids claim Harry's absence from the public eye is because the prince, 27, has been kept hidden by an unlikely source, his one-time rumored flame, Cressida Bonas.
"When everyone was looking for Harry, Harry was actually taking refuge with Cressida and her family," Ingrid Seward, editor-in-chief of UK's Majesty Magazine told ABC News.
Bonas, 23, is the daughter of 1960s model Lady Mark-Gaye Georgiana Lorna Curzon. Bonas and Harry were first spotted together at the London premiere of the "Dark Knight Rises" in July.
The blonde model, who bears a striking resemblance to Harry's former girlfriend of nearly seven years, Chelsy Davy, was also part of the group of young Brits who took part in a reportedly raucous vacation at the Necker island estate of Virgin mogul Sir Richard Branson just prior to Harry's Las Vegas outing.
Harry and Bonas, along with friends including Arthur Landon and Tom "Skippy" Inskip, spent a week on a private island to celebrate the 27th birthday of Branson's son, Sam, according to the U.K.'s The Telegraph.
Pictures posted from that week-long vacation include a guy wearing the same shorts that Prince Harry wore in Vegas passed out in the sand and a photo of Bonas and another girl dressed in neon bathing suits and neon-pink wigs. The pictures, along with Harry's under-the-radar Facebook account, have since been deleted.
From Necker, Prince Harry and two more from the group - Landon and Inksip, according to the Telegraph - flew on to Vegas for more partying. It was there that the prince was caught playing pool in a hotel suite room fully naked, in one photo covering his genitals with his hand and, in another, bear-hugging a naked woman.
"I gather Cressida wasn't humiliated at all," Seward said of the photos. "She knew Harry was going to [Las] Vegas. She knew he was going off to have fun."
Bonas, according to People magazine, was introduced to Harry by his cousin, Princess Eugenie, the daughter of Sarah Ferguson and Harry's uncle, Prince Andrew.
Immediately after the Vegas photos emerged, tabloids reported that Bonas was "humiliated" by the nude photos of Harry with another woman and tired of his wild side, UK's Daily Mail reported. The paper said then, however, that Bonas had not dumped Harry, only "hinted" that she wanted "some time out."
If Harry is indeed hiding with Bonas, his time away from the spotlight appears to be almost over. The prince, who was thought to have returned to his Army base in Wattisham, Suffolk, post-Vegas, is expected to return to the public eye Monday to attend the Paralympics swimming events.
