(Cover) - EN Showbiz - Zac Efron and Vanessa Hudgens couldn’t keep their hands off each other on their recent trip to Hawaii.

The High School Musical co-stars have been dating for five years. They recently splashed out £8,000 on a romantic holiday to Maui, where they shocked onlookers with their public displays of affection.

One witness said Zac, 22, and Vanessa, 21, were so “warm” there was no mistaking their strong feelings for each other.

“They were all over one another. They’re obviously in love,” the source told British magazine More. “At one point they walked along the beach holding hands and they looked so cute. They were very warm and affectionate, rubbing suntan lotion on one another and hugging.”

Zac and Vanessa spent ten nights in Maui, staying in a private villa and dining in local restaurants. They also took surf lessons at the Royal Hawaiian Surf Academy, where they were photographed laughing and holding hands as they rode the waves.

“Zac is very good and Vanessa is eager to catch up,” the source added. (C) Cover Media
