Eva Mendes wore a tarp-like paisley dress in Paris on Wednesday. What's she doing hiding her figure under there?

Eva, Katie Holmes, Jennifer Garner, Diane Lane, Amy Adams and Natalie Portman will be honored for their charity work at Variety magazine's second annual Power of Women luncheon on Sept. 30. The ladies have been selected as Lifetime Impact Honorees for making a significant difference to their chosen causes.

Eva's cause is The Art of Elysium, which encourages working actors, artists and musicians to voluntarily dedicate their time and talent to children who are battling serious medical conditions.
