Mel Gibson's girlfriend pregnant

Mel Gibson is preparing to be a dad for the ninth time.

People magazine was the first to report on Friday that the actor-director's girlfriend, writer Rosalind Ross, is pregnant. Gibson's publicist Alan Nierob confirmed the report.

No further details about the pregnancy were immediately available.

Gibson, who won an Oscar for directing Braveheart, has seven children from his marriage to his ex-wife, Robyn Moore. Their youngest child is 17.

He also had a 6-year-old daughter with ex-girlfriend Oksana Grigorieva.

Gibson's latest directing effort, the World War II drama "Hacksaw Ridge,'' debuted earlier this year at the Venice Film Festival and is due in theatres on November 4.
