Jennifer Aniston 'happy' for Brad Pitt and Angelina Jolie's engagement

With the news that Brad Pitt and Angelina Jolie are engaged, it was only a matter of time until people started wondering how a certain ex-wife would react. Well, it looks like Jennifer Aniston is A-ok with the news.

A source tells HollywoodLife.com, "Jennifer is happy for Brad and Angelina. She is so in love with Justin [Theroux], that she is really grateful how things turned out...In a strange way if it weren't for Angelina, Jennifer would not have connected with Justin in a romantic way. Jennifer is in a really wonderful place right now. I wouldn't be surprised if she even went to their wedding."

Pitt split from Aniston while he was making "Mr. & Mrs. Smith" with Jolie in 2005. They've been together ever since and have six children.

While maybe not quite yet ready to wed, Aniston is getting pretty serious with Theroux. The two first began dating while making the movie "Wanderlust" in 2010. They've since moved in together and even adopted a dog.
