Paris Hilton parties with the royals

PARTY Prince Harry and his South African girlfriend Chelsy Davy had a massive bust-up last night in front of stunned onlookers – including blonde air-head Paris Hilton.

It was an unlikely evening which saw the royals – Princes Harry and William and cousins, Eugenie and Beatrice – rubbing shoulders with American singing sensation Christina Aguilera and reality TV star Paris, in town to find her new BFF (Best Friend Forever).

The usually happy lovebirds were spied exchanging a heated words at Whisky Mist after spending the evening separately, despite being in the same venue.

Chelsy, 23, spent the evening with her friends, while Harry, 24, concentrated on partying with his mates and chatting to Paris.

A source told theBuzz: “Chelsy arrived after Harry, but failing to spot him, spent the night with a group of pals. They looked like they were having a great time, dancing around to Ain’t No Mountain High Enough by Diana Ross.

“It was only when Harry had put on his jacket to leave that he spoke to Chelsy. They were exchanging words – neither of them looked very happy. Harry was shouting and pointing towards the entrance.”

The situation only calmed down when friends of the couple gathered round and a pal grabbed the prince by the face, pulling him in for a hug.

“It seemed to have a calming effect on both of them,” said the onlooker.

Harry was at the Park Lane club with Paris, who has admitted to fancying Prince William in the past, before transferring her affections to Harry, favouring his similar partying lifestyle.

“Paris was introduced to Harry and the pair exchanged polite air kisses, before exchanging a few words,” a source told us.

But it seems Paris, 27, has returned to liking her original Prince.

“She started doing this really stupid dance, basically shaking her ass in front of Prince William.”

Her dance may have done the trick and she was soon introduced to Wills, 26, and spent a while chatting to him.

Meanwhile, it seems mum-of-one Christina wasn’t having as great a time out and was spotted looking rather glum.

But as usual Princesses Beatrice, 18, showed them all how it should be done and stayed out partying long after the rest had left.
