Back in each other's arms! Bikini-clad Vanessa Hudgens shares a steamy kiss with boyfriend Austin Butler as they are reunited in Hawaii

She's been promoting her latest movie Journey 2: The Mysterious Island, with her ex Josh Hutcherson and causing some confusion with the Australian press as to who's dating who.

But today, the bikini-clad 23-year-old was reunited with her current boyfriend Austin Butler in Hawaii, leaving onlookers with no doubt as to who has Vanessa 's heart now.

The couple, who have been dating since last September, are clearly very much in the honeymoon period of their relationship.

The High School Musical actress, who also dated co-star Zac Efron, looked stunning as she sported a tiny red string bikini in Hawaii.

She showed her athletic figure in the attire which she paired with some wooden-style jewellery accessories.

Vanessa and fellow Disney actor Austin, 20, frolicked in the ocean together, kissing and cuddling.

Their lovey-dovey behaviour akin to the last few weeks, with the couple just unable to keep their hands off each other.

When Vanessa and Austin started dating last year, friends said at the time that it was 'nothing serious', but the pair now seem to be inseparable.

They holidayed in Miami last month, visited Disneyland in Anaheim, California, and spent Christmas and New Year's together too.

Austin, who recently co-starred in the movie Sharpay's Fabulous Adventure, alongside Vanessa's best friend Ashley Tisdale, is three years younger than Vanessa.
