Zac Efron: Birthday Piggyback Ride for Ashley Tisdale!

Zac Efron helps Ashley Tisdale celebrate her 26th birthday by spending time at the beach by a friend’s house on Saturday (July 2) in Malibu, Calif.

The 23-year-old actor went shirtless as he gave a bikini-clad Ashley a piggyback ride from the beach to the water. When they got back to the house, Zac walked around with Ashley on his shoulders!

“So happy zacary [sic] made it to my party!!! He’s my brother/best friend!!!” Ashley tweeted.

Ashley also thanked her fans for birthday wishes. “Thanks to all the fans for ur amazing birthday wishes!!! U r the best! I love you! I am so grateful 4 u all. #wouldntbewhereiamwithoutyou,” she wrote.
