Aguilera feels guilty for not doing enough charity

After visiting Kigali, Rwanda, on a hunger relief mission in June, singer Christina Aguilera feels she should have done more charity work.

The 32-year-old cannot get over the poverty she saw there and is touched by what she saw and wishes she had done more before returning to the US.

"The trip came at a time when I really needed to step away and connect with bigger issues in the world, (and) this trip really touched me in a way I never felt before.

"I came home and really wondered about why some people are born to some situations and others are born in a different place," People magazine quoted Aguilera as saying.

"I had to come to terms with a little guilt even for coming home and not doing more. The people of Rwanda touched me in a way I cannot express or put into words. They are in a place that needs our help and I am so proud of the work that we are doing there," she added.
