Is Mel Gibson's girlfriend pregnant?

Mel Gibson's girlfriend Oksana Grigorieva is pregnant with the actor-director's child, according to TMZ.

An inside source told the gossip news website that Grigorieva, a 39-year-old Russian singer with Gibson's Icon Records label, is with child and already in the second trimester of her pregnancy.

But there is no official confirmation or response from Gibson's camp to this news.

Gibson's wife of 28 years, Robyn, filed for divorce on April 13.

Robyn and Mel, who have seven children together, reportedly had been separated for about two years.

Oh, and Grigorieva has another child, a son, 11, from actor Timothy Dalton.
