Julianne Hough stays close to costar Kenny Wormald as they attend a Footloose screening at the Ritz East theater on Thursday (September 8) in Philadelphia, Penn.

The 23-year-old actress and singer also let out a hoot and holler as she participated in a Q&A after the screening.

Julianne has teamed up with Viacom to participate in a national day of service campaign to help commemorate the 9/11 terror attacks.

Julianne, along with other artists including Lady Gaga, Jordin Sparks, and Drake Bell have recorded a public service announcement in which they reflect on the question, “Ten years later, what will you do to remember?”
