Tisdale looked great in a yellow bikini and denim shorts, celebrating her day with BFF Selena Gomez ... who showed up to the beach party sans boyfriend Justin Bieber.
The partying wasn't over once the sun went down though. Vanessa Hudgens joined the group for a dinner in Malibu followed by a bonfire on the beach.
