Ashley Tisdale rang in 27 with some of young Hollywood’s biggest stars.

Set with a fête at a house in Malibu, the Miss Advised co-executive producer was joined by her man Scott Speer, along with Selena Gomez (who came solo, but brought some of beau Justin Bieber‘s pals) and Vanessa Hudgens and beau Austin Butler.

Sipping on Coco Brevé alcoholic beverages throughout the day, Tisdale and Speer showed “lots of P.D.A. action,” an onlooker tells PEOPLE.

The birthday girl, clad in a yellow fringe bikini, and short jean cutoffs, took to Instagram to express her happiness over the celebration.

“Magical night at the beach!” she wrote, accompanying a bonfire photo. “#birthdaygirl.”
