High School Musical star Ashley Tisdale has warned potential suitors she won't stand for jealously in a relationship - especially against her co-star Zac Efron.

The 23-year-old is looking for a potential boyfriend, but has been put off because most young men get envious when they see her surrounded by Hollywood hunks, particularly her Disney pal Efron.

She tells America's Seventeen magazine, "I'm always surrounded by good-looking guys, like Zac Efron. So I have to be with someone who's not going to get jealous about any of that, or when I'm kissing somebody in a scene."

And Tisdale insists the man in her life will have to come to terms with having Efron around - because they've been friends for years.

She says, "He's so funny, and you can just chill and hang out with him. We met years ago through a mutual friend, so we were friends for a long time before Hsm (High School Musical)."
