Actress Evan Rachel Wood was baffled to discover she has a loyal fanbase on - because she doesn't even use the social networking site.
The Wrestler star admits she barely knows what the online craze is all about - so anyone purporting to be her on Twitter is an impostor.
She tells MTV, "People ask me that (about using Twitter)! And I'm like, 'Is it a thing that I'm doing that I don't realise that I'm doing?'
"I'm not on Twitter. I don't have a Twitter account. I'm not Twittering around! I didn't even know what it was. It's not me!"
