Vanessa Hudgens and Zac Efron Engaged?

High School Musical sweethearts Zac Efron and Vanessa Hudgens are alleged to be taking their relationship to a new level, with a new report claiming the couple is engaged.

The National Enquirer claims that Zac proposed to Vanessa on a trip to Japan in January, and the pair are planning on a wedding next year.

“Zac hasn’t given Vanessa a ring yet. But he’s hoping the proposal will buy him some time with Vanessa’s super-strict mom, Gina, who didn’t approve of the sweethearts living together before they were married” claims a source.

“Vanessa’s mom has been putting serious heat on him to make an honest woman of her daughter. She is old-school and doesn’t approve of Vanessa living with Zac without some type of wedding promise.”

Spontaneous wedding proposal with no ring? Unlikely, but not impossible.
