Ashley Tisdale's Beach Birthday Bash with Zac Efron!

As she was busy ringing in her 26th birthday, Ashley Tisdale got quite the welcome surprise when former "High School Musical" co-star Zac Efron turned up for the festivities.
The bikini clad Sharpay Evans actress was having a ball as she romped around the beaches of Malibu on Saturday [July 2], with the birthday celebration being topped off when Efron arrived and gave her a piggyback ride down to the water and then back up to the beach abode....


Clearly elated about Zac's presence, Tizzie happily tweeted, "So happy zacary made it to my party!!! He's my brother/best friend!!!"
Miss Tisdale also thanked her many fans for their well-wishes on her special day, as she wrote, "Thanks to all the fans for ur amazing birthday wishes!!! U r the best! I love you! I am so grateful 4 u all."
