The former "Transformers" star is reportedly pregnant with her third child and her estranged husband is said to be the father, but they reportedly have no plans to drop their divorce, reports tmz.com.

Fox and Green, who have two children together -- 3-year-old Noah Shannon and 2-year-old Bodhi Ransom -- have been close even after the former filed for divorce last August.

Sources say that "the pregnancy just kind of happened... It wasn't planned".
