Katrina, who has stayed guarded about her personal life, joined Facebook three months ago to interact with fans.
"You want your privacy, you feel, 'What I have to say to the audience is I say to my films.' It's just the nature of me being little guarded. Now, I'm on it and I've realised that there is nothing that intrusive about it and it's a lovely place to be."
While her industry peers are quite active on Twitter and Instagram, the 33-year-old actress is set to join the two platforms.
