Newly single Prince Harry is partying in the USA!

Yes, the roguish young prince is said to have gone out for a night of clubbing and carousing last night in Miami, as a kind of curtain-raiser for his pal Guy Pelly's wedding celebrations.

No pictures of him cavorting naked in hotel rooms have yet been received by the Royalist.

But we live in hope.

Twitter user Lesley Abravanel tweeted: "Saw Prince Harry tonight having a proper dinner @ Hakkasan. Now he's @ LIV looking less proper & hardly heartbroken."

Harry stopped in at Hakkasan - in the Miami Beach hotel Fontainebleau - for a fancy dinner as part of a night out believed to be Pelly's bachelor party.

Harry's USA night out adds credence to reports today that part of the reason for his split with Cressida Bonas was because she was not invited on the 'boy's night out'.

Miss Abravanel wrote on her blog in the Miami Herald:

"The party hearty prince arrived at the restaurant at 9:25 in a signature plaid shirt with a group of about 7 conservatively dressed young men and women and was escorted to a private dining room that was conveniently (for us) located near the bathrooms and visible through the restaurant's signature open shutters. Had you not known there was a member of the British royal family sitting there with his back to the opening, you'd have thought it was possibly a convention of accountants or something similarly staid. They were definitely more Palm Beach than Miami Beach..Following the dinner, Harry and co. made their way to LIV where, at 1 a.m. he was seen "having the best time."

"Again, this was no Vegas. Harry kept his plaid shirt on and danced in the comforts of his own skybox. As for pictures of this controlled debauchery, no such luck. Neither pictures nor DJ shout outs were allowed as "per his security detail." Staffers were sworn to secrecy or else it was off with their heads--and their jobs. "I wouldn't have known he was there if it wasn't for you," said one LIV employee. A far cry from the usual attention hungry celebs who play there, that's for sure. As for Harry's whereabouts and behavior today, that's to be determined.
