Zac Efron and Ashley Tisdale got pretty close this weekend while celebrating her 26th birthday. The High School Musical co-stars were goofing around on the beach in Malibu, California. A shirtless Zac showed off his ripped abs as he gave Ash a piggyback ride. The twosome looked like they were having a blast, laughing and playing in the water.

Later that day, Ashley tweeted:

“So happy zacary made it to my party!!! He’s my brother/best friend!!!”

The two were spotted later at a friend’s house — as Zac put Ashley up on his shoulders and walked around the party. Not present at the birthday party was Vanessa Hudgens, who split with Zac in December.

After the festivities, Ashley also reached out to thank her fans on Twitter.

“Thanks to all the fans for ur amazing birthday wishes!!! U r the best! I love you! I am so grateful 4 u all.”
