Mandy Moore
has always been a little sweetheart! 

The singer-turned-actress posted the most adorable throwback snap via Instagram on Thursday, posing for her school picture with one incredibly cute haircut.

"There are those bangs again. Oh and I remember being very proud to rock my Mom's childhood hand-me-down for Picture Day," she captioned the vintage pic. 

We gotta say, the shot is pretty priceless! From the 29-year-old's hairstyle to her hilariously adorable bright blue dress -- Mandy was the cutest kid. 

We think the "Because I Said So" star still really resembles her much younger self -- what do you think about Mandy's flashback photo?
