Get ready for the bride wars. Jennifer Aniston is officially engaged to boyfriend and Wanderlust co-star Justin Theroux. And now the race to the altar begins. Just five months ago Aniston's arch-nemesis Angelina Jolie got engaged to Brad Pitt. It's been seven years since the Friends actress divorced the A-list Moneyball actor. So far, neither Jolie nor Aniston have set dates for their highly anticipated nuptials, although many speculated that Jolie and Pitt were going to tie the knot last weekend at their estate in France. Meanwhile, a rep for Aniston's fiance released the following statement to People magazine: "Justin Theroux had an amazing birthday on Friday, receiving an extraordinary gift when his girlfriend, Jennifer Aniston, accepted his proposal of marriage." The Hollywood hunk, who turned 41, first stepped out with 43-year-old Aniston back in May 2011. The good news is that when Theroux and Aniston finally say "I do," he will be carrying her over a pretty expensive threshold. The couple recently closed on a mega real estate deal and are now the proud owners of a $21 million home in California. This will be the first marriage for Theroux and the second for Aniston.
