Harry, 27, showed off his crown jewels to a room full of women - and one sneaky rogue camera - while potting some balls in a VIP hotel suite.
In one of the snaps, published on US website TMZ, the Prince is cupping his privates while a topless girl stands behind him.
In another, the red-haired hottie is stood starkers cuddling a woman - who also appears to be bare - from behind.
It's not yet been revealed who the lucky ladies are, but the pictures are genuine.
A spokeswoman for St James's Palace said they would not be commenting on them.
Harry has been partying in Las Vegas for several days, staying in an exclusive £5,000-a-night suite at Wynn Resort.
Former Head Of Royal Protection officer at the Met, Dai Davies, described the Prince as a "lovely man", but admitted it was "a nightmare" to control him and other young royals sometimes.
Mr Davies told The Telegraph: "He's a young man with lots of testosterone but there is a balance and occasionally that balance slips."
