Angelina Jolie and Brad Pitt announce their engagement

A representative for Angelina Jolie and Brad Pitt – whose engagement was confirmed yesterday – revealed the Brangelina brood is “very happy” as their famous parents are set to wed.

Angelina Jolie, 36, recently revealed in an interview how their kids often asked why there were not married “like Shrek and Fiona”.

With the news, the couple’s seven-year commitment will be all the more clear for their youngsters to see.

Robert Procop, a private jeweller for the couple, revealed earlier today that he designed an engagement ring for Angelina Jolie under Brad Pitt’s guidance.

And Brad Pitt’s spokeswoman Cynthia Pett-Dante later confirmed the news, saying: “It is a promise for the future and their kids are very happy. There’s no date set at this time.”

Angelina Jolie was spotted wearing the ring on her wedding finger at the Chinese Art collection at the LA County Museum earlier this month, where she was pictured with Brad Pitt, 48, and their son Pax, eight.

A spokesperson for the jeweller announced the news to the world, saying: “I can confirm that, yes, Robert Procop did indeed design an engagement ring for Angelina Jolie, designed in collaboration with Brad Pitt.”

Robert Procop said: “Brad had a specific vision for this ring, which he realized over a yearlong collaboration. He wanted every aspect of it to be perfect, so I was able to locate a diamond of the finest quality and cut it to an exact custom size and shape to suite Angelina’s hand.”

He continued: “Brad was always heavily involved, overseeing every aspect of the creative design evolution.

“The side diamonds are specially cut to encircle her finger. Each diamond is of the highest gem quality.”

Experts estimate the ring cost around $250,000.

Angelina Jolie’s father Jon Voight was among the first to publicly congratulate the pair, telling Us Weekly: “I’m very happy for them.”

Angelina Jolie has been married twice before – to British actor Jonny Lee Miller between 1996 and 1999 and then Billy Bob Thornton, from 2000 to 2003.

Brad Pitt’s marriage to Jennifer Aniston lasted five years before they announced they were divorcing in early 2005 – which came after he had met Angelina on the set of Mr. & Mrs. Smith.

Brangelina – as they became known – quickly became a Hollywood power couple, with a brood of six children; five-year-old Shiloh and twins Knox and Vivienne, aged three, along with three adopted children Maddox, 10, Pax, eight, and Zahara, seven.

Angelina Jolie and Brad Pitt once insisted they wouldn’t wed until the legalization of same-sex marriage in America.
