Living up to his reputation for being the "party Prince", Prince Harry has been hanging with A-listers as he partied up a storm with a bevy of stars. The 31-year-old was the royal guest at an exclusive Ciroc vodka bash thrown by model Suki Waterhouse before Christmas.

The royal joined Cara Delevingne, actresses Sienna Miller and Margot Robbie, TV presenter Poppy Jamie and his cousin Princess Eugenie for an evening of fun and games as they all clearly got into the festive spirit.

The cool set were caught on camera larking around in a photo booth, pulling silly faces for the camera, with Sienna Miller donning a green elf's hat while Harry showed off a bespectacled look in oversized frames.

A source told the Sun on Sunday that the Prince seemed to be enjoying a chat with Suki, with some guests suggesting that it could be the beginning of a romance. The insider revealed: "It was Suki's party and they gave each other a big hug when they saw each other. Harry seemed completely interested in what she had to say. She was very bubbly and loud while he seemed to be enjoying her zaniness and free-spirited nature. Everyone was talking about how Suki and Harry seemed particularly close, some even said there was the start of a romance brewing."

Suki most recently split up with Hollywood heart-throb Bradley Cooper, who quickly moved on to Irina Shayk, though it's been reported that Shayk and Cooper have now also called time on their relationship. Suki is very much a singleton who mixes in the same circle as the Prince and is typical of the girls Harry has previously dated.

The royal's exes have included Cressida Bonas, who he split from in March 2014 after a row over attending the wedding of Harry's good friend, Guy Pelly and Zimbabwe-born Chelsy Davy. The pair are said to have had an on-off relationship while Harry was training in the army and overseas.

He is currently rumoured to be dating an American PR-girl he met during a trip to Los Angeles over New Year. The royal, who is fifth in line to the throne, was first introduced to Juliette Labelle, 22, on a private break to her home city and they have remained in contact ever since.

Earlier Australian magazine New Idea alleged that the 31-year-old had been set up with 19-year-old blonde aristocrat Maria-Olympia of Greece and Denmark by his cousin, Princess Beatrice, however the reports were as quickly dismissed by a senior royal source.

Prince Harry has previously commented that he would like to settle down and have a family someday like his brother, but in the meantime, he is certainly making the most of his bachelor status.
