Gorgeous Halle Berry will reveal all in her new movie - without charging extra.

                 The BULWORTH beauty made Hollywood bosses cough up a reported $500,000
                 to bare her breasts in her current movie SWORDFISH.

                 But she's agreed to strip off for love scenes with Angelina Jolie's husband
                 Billy Bob Thornton in MONSTER BALL for free - provided she has final
                 approval of the raunchy shots.

                 According to Britain's DAILY STAR newspaper, a source says, "In Swordfish, we
                 got a very brief glimpse of Halle, but in Monster Ball, Halle will be nude."

                 The movie stars Berry as the wife of a jailbird played by Puff Daddy who dies in
                 the electric chair. She then has a wild fling with a racist prison guard, played by Thornton.
