"This will confirm that Oksana Grigorieva and Mel Gibson welcomed the arrival of a baby girl named Lucia on Friday, October 30, 2009 at an undisclosed hospital in Los Angeles," the spokesman said in a statement.

He declined to give any additional details.

Gibson, 53, has seven children with his first wife Robyn, who filed for divorce in April after 28 years of marriage.
