Best pals Ashley Tisdale and Vanessa Hudgens have cemented their longtime friendship by sharing tattoo time in New York.

The former High School Musical co-stars visited Manhattan skin art parlour East Side Ink last week (ends09Sep11) for a joint late-night session with revered tattoo artist Bang Bang.

Tisdale had "jamais seule," French for "never alone," tattooed on her foot, while Sucker Punch star Hudgens had the symbol for "Om" inked on the back of her hands.

The two pals agreed on the tattoo trip while attending New York Fashion Week together.
