The 19-year-old actress, who was there to rep Insidious: Chapter 3, ran into her Jem and the Holograms co-star Ryan Guzman at the after party held at Club Nokia.
Faking It‘s Katie Stevens was also seen at the event, showing off a little leg in a fringey dress.
FYI: Katie wore a Zeynep Erdogan dress, Alexandre Birman heels, Lillian Shalom clutch and Kimberly McDonald jewels. Stefanie wore MILLY.
