Mia Talerico is heading into her senior year of high school, and she marked the occasion with an Instagram post on Aug. 19, according to E! News.
The Good Luck Charlie alum shared photos of herself on what she called her “Last First Day,” posing in a pink shoulder-free top and jean shorts while holding a sign for the milestone.
In her caption, the 17-year-old wrote, “Now I'm starting to feel old.” Fans who have followed her since her Disney Channel days responded with surprise at how quickly she has grown up.
Talerico played Charlie Duncan on Good Luck Charlie from 2010 to 2014. She has said in the past that it feels surreal to be recognized by people who watched her grow up on screen, and that seeing the show again can feel like looking through a family scrapbook.
