Angelina Jolie has been seen wearing her diamond engagement ring for the first time after announcing at the weekend that she had become engaged to Brad Pitt.

The actress was photographed with Pitt and their children at an event in the Los Angeles County Museum of Art wearing her huge diamond ring, which was designed by her fiance.

Pitt worked with her favourite jeweller Robert Procop for over a year to create the design, which features a large central diamond set into a wide textured band.

It is predicted that the ring cost Pitt over $250,000 (£157,000).

Jolie showed off her ring by teaming it with a pair of classic wide-leg black trousers and a cream silk blouse.

She kept the rest of her accessories simple, by adding just a black ladies designer watch that was worn on her left wrist.

It is not the first time that Jolie has had an engagement ring, as she has previously been married to actors Jonny Lee Miller and Billy Bob Thornton.

Pitt has also previously been married to Jennifer Aniston.
