Vanessa Hudgens has told boyfriend Zac Efron she wants to date other men.

The 20-year-old actress - who met her 21-year-old beau when they were both starring in 'High School Musical' - was reportedly livid after hearing Zac doesn't want to get married until he is 40, and decided to make him jealous by seeing other people.

After discussing the matter with her friends, Vanessa is believed to have told Zac she wants the freedom to go out with other guys.

The source added to National Enquirer magazine: "Zac's totally upset - he doesn't want Vanessa dating anyone else. Even though he's not ready to commit himself to settling down at this stage of his young life, the thought of Vanessa in another man's arms drives him crazy."
