Paltrow coy about pregnancy

Hollywood beauty Gwyneth Paltrow has responded coyly to probing about the stage of her pregnancy at a screening of new movie Proof.

Speculation surrounding her expanding waistline has been rife in recent months, until confirmation Paltrow and Coldplay singer Chris Martin are expecting a second child came last week.

But despite allowing actor Lou Diamond Phillips to introduce her to the Proof audience on Thursday as a "pregnant woman", the blonde star was cagey about precise details.

Celebrity TV show The Insider reports she laughed off Phillips' curiosity about how far along she was, saying simply: "Far enough along to feel very cumbersome."
