Angelina Jolie may be gearing up for her wedding to long-time love, Brad Pitt, but she just got a boost in her other love affair, humanitarian work. Jolie has been named a special envoy  for the U.N. High Commissioner for Refugees. 

In her new role, she is expected to focus on large-scale crises resulting in the mass displacement of people, UNHCR spokesman Adrian Edwards said at a news conference in Geneva. I don't think you need a rocket scientist to see the benefits that she is bringing in terms of the attention that she is getting for the plight of the world's displaced.

Jolie has been involved with the U.N. over the past 10 years and has focused on refugees and bringing attention to their plight. She will now represent the UNHCR at the diplomatic level to governments and diplomats.

Jolie and long-time beau, Pitt, announced their engagement on Friday after Jolie was spotted with an engagement ring earlier in the week.

Yes, it's confirmed, Pitt's manager Cynthia Pett-Dante told People Magazine. It is a promise for the future and their kids are very happy. There's no date set at this time.

Pitt popped the question with a specially designed ring. It is said the ring is anywhere from 10 to 17 carats and is valued from $250,000 to $1 million.

Brad had the vision for the custom-cut engagement ring, Beverly Hills jeweler Procop told People Magazine.

Jolie and Pitt have been together for seven years and have six children together.
