Along with Diane Lane, Amy Adams and Natalie Portman, the three actresses will be honored with Lifetime Impact for their philanthropic works.
Katie Holmes, Eva Mendes and Jennifer Garner are to be honored for their charity work at Variety magazine's second annual Power of Women luncheon. The event, which will take place at Los Angeles' Beverly Hills Hotel on September 30, will also fete actresses Diane Lane, Amy Adams, Natalie Portman and talent manager Suzan Bymel.
The ladies have been selected as the industry publication's Lifetime Impact Honorees for making a significant difference to their chosen causes. Holmes will be honored for her work on behalf of the Dizzy Feet Foundation, Mendes for Art of Elysium and Garner for Save the Children.
Meanwhile, Adams will be recognized for her efforts with Ghetto Film School, Lane for Heifer International, Portman for charitable microfinance organization FINCA, and Bymel for her contributions to Global Creative Forum.
The group follows in the footsteps of last year's first-ever honorees, including Christina Applegate, Anne Hathaway, Sigourney Weaver, Christina Aguilera, and movie mogul Sherry Lansing.
