Penelope Cruz has been forced to return baby gifts from family and friends in her native Spain - because she's not pregnant.

Reports suggesting the Oscar winner is expecting boyfriend Javier Bardem's baby have been flying around the Internet for weeks, but she insists they're wrong and she's not with child.

The 35-year-old walked out of a TV interview at the Toronto Film Festival in Canada on Thursday, when she was asked about the rumours, and now she's keen to set the story straight.

She says, "I start getting some presents from friends saying, 'Congratulations, you're pregnant.' And I say, 'No, I'm not, so (I) return the presents. It's amazing."
