Keira Knightley failed to see Twitter's appeals. In a new interview with Harper's Bazaar U.K. for its latest issue where she graced the cover, she revealed that she once secretly joined Twitter using a pseudonym only to delete the account 12 hours later.

The "Anna Karenina" actress said Twitter was not for her. "It made me feel a little bit like being in a school playground and not being popular and standing on the sidelines kind of going, 'Argh,' " the notoriously-private star explained.

She did not regret her decision. "No, I think that's fine," she said. "I like being private. I haven't asked a lot of the actresses who I really admire, 'How do you do it?' because I don't want to know. Maybe I'm childish in that way; I just don't want to know about your life."

Keira is not the only celeb who fell out of love with Twitter after brief trial. Early this year, Megan Fox quit the social network after only one week. She joined the micro-blogging site amidst death hoax, but she apparently found it too much to handle.

"Some of you may, or may not have noticed by now that my Twitter account has been shut down...," she wrote on Facebook back then. "I thought that 2013 might be the year that I finally blossomed into a social networking butterfly... but as it turns out I still hate it. Love you guys but I will just never be that girl. Facebook is as much as I can handle. #I'm Sorry."
