We always love when old cast mates join together years later.
And the latest is High School Musical's Corbin Bleu and Lucas Grabeel (a.k.a. Chad and Ryan).
The pair were back together for Corbin's birthday today and of course, made the reunion Instagram-official.
Taking to the social media site, Lucas shared a group pic and captioned it: "For @corbinbleu's birthday we decided to save the world… with 7.40 to spare."
The gang enjoyed a day out in LA's Room Escape, where people have 60 minutes to find their way out of a locked room by completing brain teasers, much like The Adventure Rooms over our side of the pond.
One thing is getting us down though; we have aged a hella lot since High School Musical first aired but LOOK at these two lads… faces as fresh as daisies.
