Zac Efron and Vanessa Hudgens will get back together, according to their friends.

The couple - who met on the set of 'High School Musical' - recently ended their four-year romance after growing apart but their pals are hopeful it won't be long until they reconcile.

One friend told "They realise that they both can trust each other, and there will be a Bond between them forever. Career demands, distance and wanting to enjoy being single are the main reasons for the break-up. I'd be shocked if they don't get back together someday."

While they may no longer be an item, Zac, 23, and 21-year-old Vanessa are still close and spending a lot of time together.

The source added: "They have hung out with each other as recently as two weeks ago and will continue to hang out, since they are best friends."

The break-up is said to have been amicable and the pair just realised it was time to end things.

One friend said: "They are still talking and still friends. There's no drama. No one cheated. They just grew up."

Zac recently gushed about his relationship with Vanessa but admitted he was pleased they didn't live together.

He said: "When we're filming we spend a lot of time apart, but that's what keeps it fresh you know? Also, when you're working you need to be really focused. At least I like to be focused so that time away is important. Then when you come back it's better than ever."
