After a week of twiddling his thumbs at his Windsor barracks, Harry was back in London for another night out on Friday – with a young brunette who was a dead-ringer for his old acquaintance Natalie Pinkham.

The Prince partied until the early hours of Saturday at Amika nightclub in Kensington with a group of five friends.

Harry, who was overheard boasting that he planned to get “as drunk as possible”, ran up a £2,500 bar bill over the course of two hours and knocked back passionfruit vodka shots.

With girlfriend Chelsy Davy absent, he spent most of the night chatting to the mystery brunette, who bore an uncanny resemblance to TV presenter Miss Pinkham, who has enjoyed a number of nights out with Harry and was once pictured in an embrace with him before he met Chelsy.

But despite the remarkable resemblance, The Mail on Sunday has been reliably informed that the brunette who left the club with Harry and a male friend at 2am is not Natalie.

According to onlookers Harry, who had arrived at 11pm, spent nearly an hour talking to the girl.

“He seemed engrossed in the conversation and at one point it was just the two of them talking together. She was very pretty with long dark hair and amazingly long legs.

“They were sitting on one of the main tables at the back of the club so they were quite hidden away. There was an ice bucket filled with a magnum of Dom Perignon champagne which costs £400 a bottle on the table. Harry was drinking shots and then tall glasses of vodka Red Bull.

At one stage he said, ‘Let’s get as drunk as possible.’ Chelsy, who had been with the Prince at the club two weeks before, was thought to be in Leeds, where she is at university.”

A fellow guest said: “Harry didn’t seem to mind being out on his own. He was having a great time and by the end of the night he was dancing on the sofas.”

An onlooker said that when they left in a chauffeur-driven car, the brunette sat next to the driver while Harry sat in the back next to his male friend, who hid under his hooded top. (via Daily Mail)
