Carrie Reichert said the now-married Duke of Sussex gave her his royal underpants during his infamous night in Sin City – where he was pictured partying with no clothes on.
Now she’s decided to sell the black underwear because Prince Harry had “become such a bore”.
The 43-year-old woman is also auctioning the dress and swimsuit she wore at the time and hopes to make nearly $1-million (about R16.7m) from the sale.
Her representative told the Sunday Mirror newspaper: “Harry has become such a bore. It’s a real shame.
“When he partied in Vegas, everyone loved him and his sense of fun. At least these pants are a reminder of what he used to be like... when Harry was the fun prince.
“It’s a shame he’s all po-faced and serious these days. Even as a married dad of two, he should still let his hair down now and again – what’s left of it anyway.”
Reichert, who is now known as Carrie Royale, claimed she saw Harry, who is married to former actress Meghan Markle, completely naked and using a pool cue to play air guitar when she joined him and his friends at the Encore at Wynn Las Vegas Hotel in August 2012, and after hanging around for around 20 minutes, the prince gave her his underwear as he left.
The auction will take place at Las Vegas’ Hustler Club on August 17.
