Little Nahla is going to have a baby brother!

Halle Berry, 46, is pregnant with her second child, her first with actor Olivier Martinez, 47, sources said yesterday.

And the “Monster’s Ball” actress already knows she’s carrying a bouncing baby boy.

According to E! News, the Oscar winner is at the end of her first trimester, approximately 12 weeks along.

“Halle and Olivier are really excited,” a source told E! “It’s a blessing. They can’t wait to have a baby together.”

Berry and ex-beau Gabriel Aubry are the proud parents of Nahla, 5.

They are also currently involved in a brutal custody battle centered on Berry’s desire to move with her daughter and Martinez to France.

The request has been denied by a judge.
