The 28-year-old actress said she used to search herself online initially out of curiosity but now only does it occasionally, reported Contactmusic.
"You never find exactly what you're looking for, so I try to avoid it whenever possible. I don't spend a lot of time on the Internet," she said
"I have Googled myself before. The curiosity got the better of me... It wasn't like I started trolling the Internet and suddenly had all this self-esteem," she added.
