Penélope Cruz has kicked the habit.

“She gave up smoking about five months ago, cold turkey,” an insider close to the actress tells Life & Style. “She just decided one day she wasn’t going to smoke, and just like that, she stopped.”

And it could have been just in time: Penélope was showing a bump when she and boyfriend Javier Bardem, 40, attended a U2 concert in Paris on July 12. “She’s definitely looking heavier,” says an eyewitness. “Her boobs are bigger, and her stomach is hanging over her jeans. It could be pregnancy weight.”

Another possible sign? The Vicky Cristina Barcelona star bowed out of hosting an event at the Cannes Film Festival in May because she was sick (morning sickness perhaps?).

But don’t expect to hear wedding bells any time soon. “Penélope has this idea that marriage makes things complicated,” says the insider. “She just loves being with [Javier] and believes that’s enough.”
