Vanessa Hudgens has been linked to another star of the High School Musical franchise after stepping out with hunky actor Austin Butler.

The actress, who shot to fame in the Disney movie series, sparked rumors of a budding romance with Butler after they were spotted together at a birthday party for Ashley Tisdale's sister Jennifer at Los Angeles' Lexington Social House on Saturday.

The speculation was fuelled when Butler was later spotted leaving Hudgens' house in Los Angeles on Monday.

Hudgens split from longtime boyfriend and High School Musical co-star Zac Efron in December.

Butler starred in High School Musical spin-off Sharpay's Fabulous Adventure as Tisdale's love interest.
