Halle Berry may have starred in her final movie -- she's saying she's willing to quit showbiz entirely for the sake of her daughter Nahla.

According to Radar Online, Halle believes her fame is "destabilizing" Nahla's life, and she wants to protect her from tabloids -- such as Radar Online -- by any means necessary.

A source says, "It may seem pretty dramatic, but Halle doesn’t know what else she can do to stop the tabloids writing about her. Halle thinks that Nahla’s upbringing has been far from ideal. Her picture is taken by photographers all over the world whenever she’s with her mom, and Halle would hate to think that Nahla may come to believe that’s a natural occurrence."
