A source tells More magazine, "Mila has told Ashton she wants to be married before getting pregnant. At this point, he's ready to fully let go and start the New Year afresh. He filed for divorce so he can marry Mila and have the child he's always wanted. Ashton
took Mila to his hometown in Iowa over the holidays to meet his
family, and to announce in person that they're planning a small LA wedding this April."
