The 30-year-old 'Friends with Benefits' star, who is a Jewish, was recently hit with rumours that she is expecting her first child with Kutcher, reported Radaronline.
"(Mila) definitely wants children with Ashton and wants to raise them in her Jewish religion ...(He has) dabbled in Kabbalah, the practice of Jewish mysticism," a source said.
"But Mila's family is much more traditional and less Hollywood...They want Jewish babies and Mila wants to give them to her family. Tradition is very important to her," the source added.
"They want to have a baby now and it's far more important to them than getting married... It's a dream for Mila and Ashton, and even if he doesn't fully convert, he's very much into the idea of having little Jewish babies," the source added.
