But the young actor, who had declared at the premiere in Leicester Square that he would like a girlfriend, perhaps only had himself to blame.He said: "I don't have a girlfriend but I hope to at some point.

Despite not being old enough to drink, Emma Watson showed the more experienced celebrities how to party up a storm at the Harry Potter afterparty in Old Billingsgate Market.

The 17-year-old actress, who plays Hermione, joined her costar Daniel in celebrating the film's premiere, and they certainly didn't let the weather rain on their parade.

Co-stars Rupert Grint, 18, who plays Ron Weasley, and Katie Leung, 19, Harry's love interest Cho Chang, really let their hair down, dancing the night away to cheesy music at the bash.

He's almost 18, a movie star and worth at least £25million.

Oh, and didn't Daniel Radcliffe mention he's also looking for a girlfriend?

The resulting throng of girls around the Harry Potter star appeared to be auditioning for the role.

Hemming him in on all sides, they smothered him in attention, asking for his phone number, for a peck on the cheek, an autograph, or to pose with them for a picture. Such was the attraction that extra security was needed for Radcliffe at the private party to celebrate the European premiere of Harry Potter and the Order of the Phoenix.

While thousands of screaming fans were safely kept outside, it was the mothers, wives, girlfriends, sisters and daughters of film industry executives who mobbed Radcliffe at the party.

The celebrations, at a converted warehouse in Billingsgate, East London, had been strictly invitation only, with no media allowed.

Cast and crew usually use such occasions to let their hair down away from the public eye. He spent three hours cornered by girls, having to stand up every few moments to pose with the admirers who formed a queue to meet him. On and on it went, with Radcliffe occasionally having to be escorted by two security guards to the mens' room.

By 2am he looked like he had lost the will to live as yet another admirer asked him to pose for a picture.
