Brian Austin Green has "nothing planned" for the arrival of his third child with estranged wife Megan Fox.
The 'Anger Management' star - who already has two sons, Noah, three, and Bodhi, two, with the 29-year-old beauty and 14-year-old son Kassius Lijah Marcil-Green with former partner Vanessa Marcil - admits he has never mapped out the births of any of his children before and just takes each day as it comes.
He said: "You know, nothing is planned. None of them are ever planned. You kind of just go with it."
Meanwhile, Brian - who turns 43 in July - also thinks it is "crazy" that he's going to be a father-of-three babies so late on in life.
He told PEOPLE magazine: "At my age, to be having three babies, is crazy. I'll be 43 this year."
The pair - who split up last year - have reportedly put their divorce on hold because of the pregnancy.
A source previously said: "This pregnancy was not planned, but when they found out they were extremely happy.
"Megan and Brian love being parents. They are working really hard to be together and one unit--not only for their children, but also for each other. They are looking forward for the arrival of their new baby. Brian has been a great partner and father."
Despite filing for divorce in August of last year, Megan and Brian are believed to be sharing a rented home together in Bel Air with their two sons.
A source shared: "It's a small, unassuming house, but it's private and has great views. They are living together ... They do their day-to-day stuff like grocery shopping and taking their kids out together."
