Berry told "Access Hollywood" presenter Nancy O'Dell, who is just getting back from maternity leave herself, "Yes, I am three months pregnant."
The Oscar-winning actress met her model boyfriend, Gabriel Aubrey, in 2005.
"Gabriel and I are beyond excited, and I've waited a long time for this moment in life," Berry told O'Dell by e-mail. "Now the next seven months will be the longest of my life!"
The “X-Men” and “Perfect Stranger” beauty was preparing to headline "Tulia," a movie about a drug and racial profiling scandal in Tulia, Texas.
However, due to the 41-year-old actress’s pregnancy, the film will not start shooting next month as planned, a source told TMZ.com.
The film, which was to be directed by John Singleton and co-star Berry’s “Monster’s Ball” love interest, Billy Bob Thornton, has not been shelved entirely and producers may decide to pick it up at a later date, the source said.
