Kim Kardashian Jennifer Love Hewitt charity Antonio Villaraigosa

Kim Kardashian put on her casual clothes and kept her hair in a braid while working at the Los Angeles Mission ... serving hot meals to those in need.

The 31-year-old reality star Tweeted:

    Just left the LA Mission. Met so many kind hearted people! They're goal is to feed 120,000 people by the end of the yr! We fed so many today. Everyone of us can do something small that will make a huge difference to someone else.
