The 26-year-old actress was joined for the big night by her friends Ashley Benson and Esther Houston.
Before beginning her night of celebrating, Vanessa shared an inspiring message with her fans via social media.
“Here’s to new beginnings with old, loyal friends. To being young and reckless no matter what you’re age is. To writing your own love story, in the most spontaneous moments. To being brave enough to dream big, and turning those dreams into reality. Here’s to knowing yourself a little bit better, and loving yourself a bit more. Here’s to you,” she posted on Instagram.
