Zac Efron 'proposes to Vanessa Hudgens'

Zac Efron has proposed to his High School Musical 3 co-star Vanessa Hudgens, it has been claimed.

Efron popped the question last month while the pair were on a trip to Japan together, the National Enquirer reports.

A source said: "Zac is relieved to be out of the pressure cooker, because Vanessa's mother has been putting serious heat on him to make an honest woman out of her daughter.

"She is old-school and doesn't approve of Vanessa living with Zac without some type of wedding promise.

"Gina already considers Zac a part of the family. So she's happy that he proposed."

The source added that the couple "gel really well together".

Earlier this month, it emerged that Efron had bought a home in Hollywood for around $1 million.
