Wondering whose celebrity relationship ran out of steam before the year was out? Here are the juicy details of the most shocking Hollywood breakups of 2005.
Brad Pitt and Jennifer Aniston
It wasn't until he began filming Mr. and Mrs. Smith that things took a turn for the worse. People claim that he got a little too friendly with Angelina Jolie and his marriage was never the same again. Amidst a media storm of rumors, Brad and Jen filed for divorced shortly thereafter.
Nick Lachey and Jessica Simpson
When Nick Lachey and Jessica Simpson signed on to star in MTV's reality show Newlyweds, they probably didn't realize what they were in for. This couple had no choice but to iron out their marital issues in front of millions of people.
They fought and made up and repeated the painful cycle over and over again. Nick was a conservative guy who was careful with his money. Jessica was a party girl who lived to shop. They tried so hard to change each other that it eventually drove them apart. They officially separated and now seem to be calling it quits for good.
