The `What Women Want` star - whose girlfriend Oksana Grigorieva gave birth on Friday (30.10.09) - has announced the couple plan to call the infant Lucia.
A representative for Mel confirmed: "Oksana Grigorieva and Mel Gibson welcomed the arrival of a baby girl named Lucia on Friday, Oct. 30, 2009, at an undisclosed hospital in Los Angeles."
Mel, 53, took a break from filming `The Beaver` while Oksana was in hospital and was given a rapturous welcome when he returned to the set on Monday (02.11.09).
A source on set said: "Everyone sang `For He`s A Jolly Good Fellow` and he blushed."
A friend added: "Everything is great! They couldn`t be happier. Everyone`s healthy and thrilled. He loves it!"
Although this is their first child together, both Mel and Oksana, 39, are already parents. The `Braveheart` star has six sons and a daughter with former wife Robyn - who filed for divorce in April this year after 28 years of marriage - while Oskana has a 12-year-old son Alexander with actor Timothy Dalton.
