The 22-year-old actress is not sure she wants to commit to a social media forum such as twitter - despite having a verified account on the site - but would like to keep an online journal of her opinions on fashion and beauty.
She told website JustJared: "I donЭt know about twitter. I donЭt want to tell people what IЭm doing every second. But I do want to start a blog on my Facebook.
"ItЭd be fun to blog about fashion, beauty, and just things I like. Kind of a lifestyleblog."
As well as wanting to write a blog, Vanessa - who split from her `High School Musical` co-star Zac Efron in December after five years of dating - recently revealed she would love to star in TV musical drama `Glee`.
She said: "I totally would. I`m all for musicals. I love what they are doing. I`m very go with the flow, so if it happens, awesome!"
The brunette beauty will have plenty to write about in her new blog as she told pals at the Cannes Film Festival that she is planning to relocate to New York from Los Angeles.
A source said: "She was super excited about it. She was also excited to hang with Rosario Dawson. The girls are working together soon."
