STEWART LAUGHS OFF PREGNANCY RUMOURS

Stewart admits she was stunned when several U.S. tabloids sensationally claimed she was pregnant with her co-star Robert Pattinson's baby - because they aren't even dating.

The actress has laughed off the stories and reveals all the rumours were started when she was spotted with a button undone on her jeans.

And Stewart is perplexed by how such a small detail can be so overblown by the tabloid press.

She tells Entertainment Weekly magazine, ?It's so absurd. I walk out of my trailer with my pants undone - and they think I'm pregnant? I mean, really? They think I'm pregnant? Come on! Like, dude, I don't get it."
