January 7, the world was shocked when the news broke: Brad Pitt and Jennifer Aniston broke up. After 4 and half years of happy married life, the couple finally called it quits. Sources say that both of them are handling the break-up well. They have been seen working with Jen filming Friends with Money in L.A. while brad is in Japan with George Clooney promoting Ocean's Twelve.

So what really caused the split? Rumor has it that Brad became too close to Mr. and Mrs. Smith co-star Angelina Jolie who was in Niger filming a documentary when the news broke out. A source close to Jolie said that Jolie was surprised with the news. The close relationship between the two on set of their movie might have upset Aniston, a source says. Another reason pointed out was the issue of raising a family. The couple did not have any children after 4 years marriage maybe due to the busy schedules that the two are in, making it hard to raise a family.

Since the two have called it quits, the media will keeping a close eye on the future relationships that the two might have with others. Let's just hope this time they find their match.
