As further evidence that she was the girl who had made Radcliffe's heart flutter, Cassie produced a photo of herself with him and described how they had a two-minute chat backstage.

"We said hello and had a quick chat and for the rest of the night," she said. "Just because I was fascinated, we were sort of smiling and making eye contact.

"I couldn't believe it when he said he was looking for the girl."

Cassie said she had told her boyfriend of two and a half years about Radcliffe's hunt for the mystery girl and that she would be keen to meet up with the actor again when she was in the UK.

But she said that "the night" had ended where it had begun.

"I'm not looking to cash in on his public profile," said Cassie.

"I hope people don't think I want my 15 minutes of fame or anything."

Despite the convincing evidence that Cassie was the girl who had bowled the wizard over, several others have come forward to say they were the one.

One young woman, identifying herself as Kirstie, said that she and Radcliffe had shared a 'special connection.' Another wrote: "I just want Daniel to know his feelings are reciprocated."

The romantic world of Harry Potter wizardry became more complicated when dark-haired Melbourne saxophonist Savannah Blount, 23 - the woman photographed on Radcliffe's OTHER arm during a fleeting embrace with Cassi backstage - said she was the girl who really caught Radcliffe's fancy at last year's Australian film industry's glittering night.

What's more, she would by happy to date Daniel, unlike blonde trumpet player Cassi, who already has a steady boyfriend.

Ms Blount said she was charmed by the teen wizard and would be happy to go on a date with him if the chance arose during one of her regular UK tours.

"He was quite lovely. He was very charming, very polite," she said in Melbourne. "Maybe if I was working over there or touring, you never know." Though not a Harry Potter fan, Blount is attracted to the wealthy, good-looking young actor.

"Handsome? Yes, yes - and very short. I'm more for the taller type of guy."
