Jolie and Pitt are engaged to marry, a spokeswoman for Pitt said on April 13, 2012.

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

Jolie was photographed this week wearing a large diamond ring on her engagement finger. Pitt and Jolie have been a couple since 2005, and are raising six children together, but they have never married.
