One of HARRY POTTER's magical pals cast a spell on ZAC EFRON while the HIGH SCHOOL MUSICAL hunk was in the U.K. last week.
Efron left girlfriend Vanessa Hudgens behind in Los Angeles while he travelled across the Atlantic to promote new movie 17 Again in London - and struck up a fast friendship with redhead Bonnie Wright, who plays Ron Weasley's sister Ginny in the Potter films.
The pair met at the premiere on Thursday night (26Mar09) and was then spotted enjoying during a late-night liaison on the backstreets of London
One superfan, who followed Efron from the Leicester Square cinema, tells WENN, "It was about 11.30pm and he walked up to this car and waited for someone to get out. I didn't recognise her at first, but it was that girl in the Harry Potter movies. I saw her earlier on the red carpet and she was really sweet and signed lots of autographs."
