Halle Berry is reportedly pregnant with her second child.

The Oscar winner gave birth to baby daughter Nahla in 2008 and now she's expecting boyfriend Gabriel Aubry's second kid, according to America's Life & Style magazine.

The actress, who turned 43 on 14 August, is three months pregnant.

A source tells the publication, "Halle is overjoyed. The first time, she struggled so much to get pregnant and eventually conceived through in vitro fertilization. This time, the baby was conceived through artificial insemination.

"She’s just ecstatic to be pregnant again. She wasn’t sure if she’d have another baby, so she’s very happy."

Berry's publicist has yet to respond to the story.
