Mel Gibson welcomed his eighth child late last week.  We have learned that his girlfriend Oksana Grigorieva gave birth to a baby girl, according to RadarOnline.

The baby, born a few weeks earlier than expected, arrived on Friday and is said to be healthy.  In fact, the news source reports that the newborn is already at home with her parents.

Robyn Gibson filed for divorce in April 2009 upon learning of the extra-marital romance and pregnancy of Mel's girlfriend.   The couple were married 29 years and their marital assets are estimated to be $900 million.  They have six sons and one daughter together.

Grigorieva, an accomplished musician, has a 12-year-old son Alexander with actor Timothy Dalton.
