Los Angeles: The 24-year-old, who has previously dated his 'High School Musical' co-star Vanessa Hudgens, still has fond memories of the teenage girl who used to watch over him and his brothers when they were children.

"Her name was Brook. I guess she was in high school and I was 12 or younger," a website quoted Efron as saying.

"I had a really big crush on her. She was really spontaneous and fun. I guess I did have my young love. Me and my brothers did everything to impress her which was ridiculous really," he added.
