This week, one of Hollywood's young "it" couples finally announced their heartbreaking split.


That's right, in case you missed it, 20-year-old Miley Cyrus and 23-year-old Liam Hemsworth finally confirmed that they had called off their 16-month engagement -- and the world rejoiced ... and then cried ... and now is fuming over reports that Hemsworth has already moved on with new lady, Eiza Gonzalez.


But this celebrity breakup wasn't the only one to cause complete and under chaos around the globe. Do names like Robert Pattinson and Kristen Stewart ring a bell? Or how about Brad Pitt and Jennifer Aniston?


Let's face it, we all know these star splits were more newsworthy than the actual relationships:

    After meeting on the set of "The Last Song" in 2009, Cyrus and Hemsworth began dating. They got engaged in May 2012, but were constantly surrounded by breakup rumors.

    It was assumed that after years of being a bachelor, Clooney would finally settle down with his longtime girlfriend Stacy Keibler. But to everyone's surprise (or not?), the pair called it quits in July 2013 after two years of dating.




  • Jennifer Aniston & Brad Pitt


    It was the breakup to end all breakups. In fact, though it's been many years since Brad Pitt and Jennifer Aniston called it quits, people are still rooting for them to get back together. (And by people, we mean us.) But, Aniston is happily engaged to Justin Theroux, while Pitt is set to marry Angelina Jolie.

    Their courtship and fairytale wedding were pretty high profile, but since they tied to knot, Tom Cruise and Katie Holmes kept their love low-key. Since announcing their split in June 2012, a media firestorm has surrounded the pair -- and continues to burn. (And probably will forever).

    Halle Berry's ongoing court battle with her ex and the father of her daughter, Gabriel Aubry, turned so nasty that it's hard to remember when these two were actually happy together. Still, Berry is overjoyed now and currently expecting her second child, her first with husband Olivier Martinez.




  • Kelsey Grammer & Camille Grammer
