Brad Pitt Worried For Angelina Jolie When He Proposed

Brad Pitt and Angelina Jolie decided to get married because of her work with the United Nations.

Apparently the couple feared she may not survive a Dangerous new mission with the UN helping to battle drug lords.

The mother of six adopted and biological children, who is a goodwill ambassador for the UNHCR refugee organisation, will be involved when the UN launches a fresh war on South American crime bosses.

A source told The Sun: ''Brad's terrified something bad will happen to her. It's why he wanted to cement things with a wedding.''

Earlier this year Angelina wrote a farewell letter to her fiance Brad after becoming scared for her life on a UN mission.

She said: ''I wrote a note to Brad and figured if anything happens he'll find it.

''They gave me a briefing and they said everybody needs to write down their blood type.''

The couple - who met on the set of 'Mr And Mrs Smith' in 2005 - have kids Knox, Vivienne, Pax, Shiloh, Zahara and Maddox together.

They announced their plans for a wedding last month.
