|Bruce Willis and Emma Hemming|
A source close to the couple - who married in 2009 - added to Life & Style magazine: "Emma is showing!"
Bruce, 56, recently said he was indifferent to having children with 33-year-old Emma as the only thing that mattered was being with her.
He said: "I'd like to have a thousand more children, or zero more children. It doesn't matter. Emma makes me feel great."
Bruce also revealed how meeting and falling in love with the British lingerie model turned his life around.
He said: "I'm the happiest I've ever been and this comes after a long period of being kind of lonely, even though I tried to convince myself I was enjoying my life.
"Before I met Emma I was very pessimistic about finding that special woman with whom I would want to spend my life with.
"I thought it would be difficult for someone like me, who is well known, to find a woman who didn't have an agenda and who just wanted to be with me because they loved me, pure and simple."
