Michael, father of Lindsay Lohan, confirmed that he is expecting a child with Major, 31, who is currently serving an eight-month prison sentence for probation violation, reported Radar online.
Michael, 54, currently has sole custody of their son Landon, 16-months, as she serves out her sentence.
Major is three-and-half-months pregnant and is petitioning to complete the remainder of her prison time at home as she is reported to have a 'high risk' pregnancy.
"She is considered a high risk pregnancy because of her history of seizures and she is not receiving the proper medication in jail," a source said.
Major, who has a history of legal troubles under her belt - including an arrest for refusing to leave a plane in 2011 and an arrest for attacking a couple in 2011, was allegedly caught driving three times over the legal limit and reportedly struggled to find her nose with her finger.
Meanwhile, Landon was rushed to hospital last week with a dangerously high fever.
