Brad Pitt, 48, and Angelina Jolie, 36, are officially engaged! ""Yes, it's confirmed,"" Pitt's manager tells USA Today.

On Wednesday, Jolie was spotted sporting a huge diamond on her left ring finger. It sure took her long enough to get that big diamond (confirmed to be designed by Pitt himself and jeweler Robert Procop). She has been with Pitt since 2005, when they fell in love on the set of Mr. & Mrs. Smith (their relationship reportedly caused Brad's marriage to Jennifer Aniston to fail).

Now, Pitt and Jolie have six children together - Maddox, 10, Pax, 8, Zahara, 7, Shiloh, 5 and 3-year-old twins Knox and Vivienne - and the kids are thrilled that mommy and daddy are planning to get married. ""It is a promise for the future and their kids are very happy,"" says Pitt's manager.

But, as far as actual plans for the wedding? ""There's no date set at this time,"" Pitt's manager states.
