Julianne Hough: Joyful Heart Foundation Gala 2013

Julianne Hough is all smiles as she arrives at the 2013 Joyful Heart Foundation Gala held at Ciprani 42nd Street in New York City on Thursday evening (May 9).

The 24-year-old actress wore head to toe Calvin Klein for the annual fete.

Founded by actress Mariska Hargitay, the Joyful Heart‘s mission is to heal, educate and empower survivors of sexual assault, domestic violence and child abuse, and to shed light into the darkness that surrounds these issues.

Across the country, big brother Derek was spotted picking up some goodies from Erewhon Natural Foods Market and a cool drink from Earth Bar in West Hollywood, Calif.
