Ashley Tisdale turned 27 yesterday -- and celebrated by showing off her fit beach body at the Kia Beach House in Malibu.
The young star was spotted on the shore with her hot boyfriend Scott Speer, who towered over her as the two showed some PDA for the cameras on the beach.
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.
