Who is her son's father?

She's never said.

I don't procrastinate...I reschedule.

id assume its her husband...

they got married the same year her son is born, so it makes sense he'd be the guy she conceived the baby with..... unless she got pregnant by someone else, broke up, met her husband, had an virtually instant engagement and arranged the wedding in no time.... lol
and on here his surname appears after her maiden name in the kids name.

It's not her husband. In fact there seems to be some debate as to whether or not she is with Patrick Leonard anymore.

Olivia's son Oliver was born in late 1995 around a year or so after she filmed "The Big Green". This was after she had broken up with Julian Lennon and before she started dating Thomas Jane in the late nineties. So somewhere in between those two relationships she had a child with someone and has probably chosen not to reveal the father's name as the child was had out of wedlock.

Olivia married Patrick Leonard several years ago sometime after her engagement to Thomas Jane was broken off. So Leonard is most likely not Oliver's father either.

Exactly. IMDB is incorrect for listing her as marrying to Patrick Leonard in 1995 as she did not marry him until years later.

I've read she and Patrick are now divorced.
