Hollywood hunk Brad Pitt has reportedly praised Tomb Raider star Angelina Jolie for her charity work as the official ambassador of United Nations High Commission for Refugees.

"Angelina contributes staggering amounts of money - staggering amounts. In fact, she probably makes money so she can give more away. That seems to be more her concern than films," Pitt was quoted by The Mirror as saying.

The 'Troy' star also said that Jolie's humanitarian trips to Africa to visit Aids victims had changed his perspective on life.

"I don't know how I can't [change] now, seeing what I've seen. It makes all the sense in the world to me," he added.
