There is speculation in the media that Angelina Jolie and Brad Pitt have secretly tied the knot. The rumours started when the beautiful actress was seen stepping out with a mysterious new ring on her wedding finger in Sydney.

The "Mr and Mrs Smith" star rocked the second mystery ring along with the first one (where she has her engagement ring) while shopping with her children in Bondi Beach, Australia, on Sunday. The Oscar winner has been wearing the gold engagement ring on her wedding finger since March.

Brad Pitt and Angelina Jolie announced their engagement in April 2012 and the actress started wearing a gold ring belonging to Brad's great grandmother since then in place of her $2500 diamond ring. The newer ring which Angie can be seen wearing now is however thicker than the previous one, according to the Daily Mail Website. See pictures of her ring on the Web site.

The couple have six children together, Maddox, 12, Pax, nine, Zahara, eight, Shiloh, seven, and five-year-old twins Knox and Vivienne and certainly have plans to tie the knot. Brangelina earlier planned to wed in their French estate, Château Miraval. However Angie has now changed the plans keeping in view the comfort of her family and she wants to tie the knot in their Los Angeles home.

In 2012, Brad Pitt has said that he wanted to get married to his partner for more than eight years soon. "The time is high. It's soon. I got a good feeling about it," told Brad to the Daily Mail then.

The rumours again started in August this year that the power couple are now planning their wedding anytime by this year end. However, Angelina is busy with the shooting of her movie second directorial effort "Unbroken" a World War II drama in Australia.

Angelina, who has arrived in Australia last month along with her children, will shoot the movie in Sydney and parts of rural New South Wales. The Universal Pictures movie scheduled for release in the US on Christmas next year.

With so much work commitments keeping Angie busy, do you think she might have followed the footsteps of Kerry Washington, Blake Lively and Zoe Saldana, who chose to get married secretly?
