What time is it? Vanessa Hudgens' birthday time!
As the actress celebrates turning 27, her High School Musical co-stars clearly have their head in the game and are sharing the sweetest messages on social media.
BFF Ashley Tisdale kicked things off early in the morning with a collage of past and present photos of the twosome posing on various red carpets over the years.
"It's my baby V's birthday!!! Wow we have been thru so much together. You have grown into such an amazing woman," she shared on Instagram. "We've toured the world together, have had many hair changes, and been part of a phenomenon. I honestly couldn't have done it without you."
