Personal life
In a 2011 interview, Vangsness described herself "as queer as a purple unicorn singing Madonna".[9] She was in a seven-year relationship with editor Melanie Goldstein, to whom she was engaged, until 2013.[10]
In 2015 she announced her engagement to Keith Hanson. Though she has been engaged to both a man and a woman, Vangsness says she doesn't identify as bisexual. "...If I were straight, I would say I was, but I don't totally understand it myself. I don't want to have an answer to something that I don't really have an answer to."[11]
Other Ventures
Vangsness serves as a spokesperson and advocate for Alex's Lemonade Stand Foundation, an organization that encourages children to fundraise and spread awareness of pediatric cancer by running their own lemonade stands.
