AJ Michalka shows off her cute military-style jacket as she arrives at the ELLE And Express “25 At 25″ Event held at Palihouse Holloway in West Hollywood on Thursday night (October 7).

The 19-year-old actress’ new movie, Secretariat, hits theaters TODAY! Be sure to head out to go see the movie about the famous race horse who won the Triple Crown in 1973.

AJ dished to JJJ during a recent interview that she might not be seen riding a horse in the film, but that doesn’t mean she doesn’t know how to ride. She actually had a horse! AJ shared, “My sister and I used to ride our horse in Washington, when we lived there. I love riding.”
