The actor's Facebook page went live on Friday morning and has already got 2.6 million likes.
In a video message posted on his page, Salman said: "A lot of people told me 'there are so many of (your) fake Facebook pages, so when are you joining it'. So here I am on this platform."
"Jitne fake pages hain woh ya toh woh join kar le is page ko or kya kahun main? 'Fake off' (So all the fake pages either just join this page or, what can I say, fake off)."
"We are opening Being Human stores all over India starting October," he added.
