Mel Gibson has become a father for the eighth time.

The 'Lethal Weapon' actor's girlfriend Oksana Grigorieva gave birth to a baby girl on Friday (30.10.09) and both mother and daughter are said to be doing well.

The baby - whose name is yet to be revealed - was due in December.

Mel already has seven children with his estranged wife Robyn, while Oksana has a son, Alexander, with former boyfriend Timothy Dalton.

In September, Oksana spoke of her excitement at becoming a mother again.

She said: "I have a 12-year-old, so I've been a mother for 12 years - and of course, there is no first time mother's trepidation as such. So naturally it's more relaxed, and I'm very dynamic so the pregnancy falls into my work schedule."

Mel, 53, confirmed the rumours of Oksana's pregnancy in May on a US talk show, saying: "This is true. We're going to have a child."

Host Jay Leno then joked the new arrival would be Mel's 29th child, prompting the 'Mad Max' star to liken himself to Nadya Suleman, who famously gave birth to octuplets last January.

Mel replied: "Well, actually eight. I guess I'm Octo-Mel."
