The 24-year-old actor was pictured while stepping out in Sherman Oaks on Sunday, July 31, reported Aceshowbiz.
Dylan took a picture with a fan who worked at a Jamba Juice and the fan gave an update on the "Teen Wolf" star.
Vanessa Denegri tweeted, "Guys I just met Dylan O'Brien... He just walked into jamba juice and I took his order I'm crying."
" "MY LIFE HAS BEEN MADE, meeting you was the best thing ever @dylanobrien," she wrote alongside a photo of her and her idol.
In March, he was run over by a car while shooting a scene involving the vehicle in Canada and broke several bones in his face. Production on the film was halted for weeks for Dylan to recover and the release date was pushed back from February 17, 2017 to January 12, 2018.
