Jennifer Aniston has selected the wedding dress for her upcoming nuptials, and she is going Valentino!

Since announcing her engagement to Justin Theroux this past summer, scads of designers have been vying for Aniston's attention in hopes of designing the gown for her big day. But word has been circulating that the former "Friends" cast member has chosen Valentino.

Reports spread Friday afternoon that the 80-year-old designer is in the process of finishing the custom wedding dress.

The 44-year-old actress has been busy as of late, planning her second trip down the aisle. According to Aniston insiders, she has also been working very closely with Valentino to create the perfect dress for wedding.

"Jen and Justin want to make it a really special day and they're very excited," one insider told Grazia magazine.

The source continued, "Jennifer has been working with Valentino on a dress and has been heavily involved in the designing process, while Justin intends to wear an Armani tuxedo."

It has also been said that the stunning red Valentino gown Aniston wore at the Oscars last month was her way of "thanking" the designer for working so hard and doing such a wonderful job with her wedding dress.

It's been rumored that Aniston and Theroux will be wed sometime in the next few weeks. The couple has been together since meeting on the set of their movie "Wanderlust."

The planned ceremony will be quaint and low-key and it has been reported that it will take place in Hawaii.

The Aniston-Theroux wedding with be very different from the actress' first.

Her 2000 wedding to Brad Pitt was very lavish indeed.

Another source said, "Jen would have liked to have done it at home in Los Angeles but it looks like that would be too difficult to keep quiet. She doesn't want to get married with photographers buzzing around her head in helicopters."

She then continued, "Justin just adores Hawaii. It's his favorite place in the world and he has a little house on the island of Kauai."

The cottage is reportedly too small for all the wedding festivities, but as they both love the island, they will hold the ceremony elsewhere.

The source also added that Aniston enjoys "the idea of a laid back Hawaii wedding in the sunshine."
