Ashley Tisdale and best pal Vanessa Hudgens hit up Lexington Social House Saturday night, where they celebrated the 30th b-day of Ashley's older sis, actress Jennifer Kelly Tisdale.
The duo were all smiles as they headed through a crowd of fans outside the Hollywood hotspot. Then, Ashley, Vanessa and friends dog-piled into their waiting car -- they had five people in the back seat, and the driver looked none too happy (see below)!
The group headed to Bob's Big Boy for some late-night, post-party burgers. See all the pics from their big night out in our gallery below!
At the hotspot, the group dined on lobster corn ravioli, steak tartare, and crispy squash blossoms, and of course, a vanilla-and-chocolate birthday cake! Yum!
