Tisdale snuck a wedding photo on her Instagram earlier today, captioning it, "Best day of my life! Introducing Mr and Mrs French! September 8, 2014"
What's even cuter is that Tisdale's High School Musical co-star/BFF, Vanessa Hudgens, was picked to be a bridesmaid, and her color scheme was Instagram flawless.
We can't wait to see who else was on the guest list. ZEfron?
