You read it here first – Mel Gibson is an Octo-Dad!

As Breaking Celebrity News was first to report on Sunday,  Mel's fiancé Oksana Grigorieva gave birth to their baby -- a heathy baby girl named Lucia.

Oksana gave birth at an undisclosed hospital in the Los Angeles area on Friday, a few weeks early but a source tells Breaking Celebrity News that everything went well and mom and daughter are doing just fine. In fact, Breaking Celebrity News has learned that mom and the baby are already home.

It was Breaking Celebrity News that first uncovered Mel’s affair with Oksana. We published a series of photos of the cozy couple in Costa Rica earlier this year, before the public had any idea that Mel’s marriage was apparently kaput.

Mel’s wife Robyn filed for divorce in April, 2009, shortly after the photos were public and Mel admitted he was romantically involved with Oksana. And once she turned up pregnant he put a ring on it. He has not announced a wedding date. (Mel and Robyn were married 29 years; their marital assets are estimated at $900 million.)

Mel has six sons and one daughter with Robyn.               

Oksana, a Russian beauty, has a son with James Bond star Timothy Dalton. She is an accomplished musician and composer who is still hoping to launch her career, and released her album Beautiful Heartache in July, through one of Mel’s companies. Mel’s money goes a long way: The once-obscure beauty recently “found” the money to hire powerhouse Los Angeles legal firm Lavely & Singer to sue a man she formerly worked on several songs. That suit has been settled.
