The Neighbors 2 star shared the throwback pic on Friday of himself with HSM cast members Ashley Tisdale, Vanessa Hudgens and Corbin Bleu on both Instagram and Twitter. "So grateful I came across this picture…With the o.g. crew during one of the most cherished and exciting times of my life. Love you guys forever," he captioned the snap.
Despite the fact that the 28-year-old actor can't remember all of the 2006 movie's hit songs, it's nice to see that he's still got nothing but love for the Disney Channel movie that made him a household name.
A number of cast members reunited in January for a special Disney Channel telecast in celebration of the hit movie's 10th anniversary. During the reunion, the cast reminisced on their favorite songs, scenes and BTS moments. While Efron wasn't there in person, he did make an appearance with a pre-recorded message to the show's fans.
Just ahead of that reunion, Tisdale told ET that she's stayed close with her co-stars, including Efron.
"I just love that we all still love each other and love hanging out with each other and have that connection," she said. "It was a really special moment in our lives."
