Keira Knightley joined Twitter but deleted her account just 12 hours thereafter, according to reports.
The 28-year-old actress told Harper's Bazaar UK that it made her feel like being in a school playground and not being popular while standing on the sidelines, Metro.co.uk reported.
The 'Pirates of Caribbean Star' said that she likes being private and hasn't even asked a lot of the actresses who she admires about how they do it, because she claims that she doesn't want to know.
