The 43-year-old's rep told The Mirrorthat Royale misses the "fun Harry".
"It’s a shame he’s all po-faced and serious these days," she told the outlet. "Even as a married dad-of-two, he should still let his hair down now and again – what’s left of it anyway."
She added: "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."
The best part? Some of the proceeds are apparently going to Harry and Meghan's charity, Archewell.
The auction kicks off at Las Vegas' Larry Flynt's Hustler Club on August 11 at a starting bid of $10,000 (£8,200). If the bidding hits $800,000 (£660,000), the lucky winner will receive a vintage bottle of 1996 Dom Pérignon Rose wrapped in 24 karat gold, worth $200,000 (£165,000).
