Zac Efron Vanessa Hudgens Engagement Imminent?

Is Hollywood heartthrob Zac Efron planning a proposal to longtime girlfriend Vanessa Hudgens?

According to well-placed spies for celebrity Gossip Guy Zack Taylor, Efron has selected an engagement ring that he will present to his former High School Musical co-star — and GF of four years — sometime in the next few weeks.

The couple have reportedly been shacking up in Efron’s Los Angeles-area home since Vanessa’s Malibu mansion suffered devastating damage in a flood back in May.

Now Zac if finally ready to take things to the next level.

“The proposal has been something [Zac] has been thinking about for a while. He already has the ring picked out and I wouldn’t be surprised if we saw the two engaged this summer,” the insider divulges.
