Halle Berry is a Cancer Fighter

Halle Berry keeps it summery and fresh in a black halter as she leaves a friends’ house in West Hollywood on Wednesday.

The 41-year-old actress has joined forces with the Callaway Golf Foundation and the Entertainment Industry Foundation as the 2008 ambassador for the Callaway Golf Foundation Women’s Cancer Initiative.

Halle will be featured in an extensive print public service announcement campaign this summer aimed at raising awareness and funds to help find a cure for ovarian cancer.

The Callaway Golf Foundation will also host this year’s celebrity golf tournament, the Callaway Golf Foundation Challenge, at the Riviera County Club in Los Angeles on December 15.
