Screen siren Sharon Stone has shunned a lead role in an upcoming thriller because she would have had to portray a woman haunted by the death of her adoptive son.

The sexy 47-year-old, who earlier this month adopted a second baby boy, politely declined the offer for the role in "Possession" because she reportedly didn't want to tempt fate, says Ireland Online.

"Sharon was concerned. She felt superstitious about playing such a character and decided playing it, was too close to home. We are now talking to Kim Basinger," James said.
