Britney Spears and Jason Trawick
"X-Factor" judge Britney Spears and fiancé Jason Trawick may have been set to walk down the aisle but rumor has it their relationship is on the rocks. RadarOnline reports that the couple may call off their wedding, assuring Spears has only two failed marriages under her belt.
Khloe Kardashian and Lamar Odom
The fact that Khloe Kardashain's marriage to Lamar Odom has lasted over three years is surprising considering the two knew each other all of two weeks before getting hitched. Yet througout the year, tabloid reports have surfaced again and again of trouble in the couple's marriage. (And as we learned with Demi Moore and Ashton Kutcher, sometimes that tabloids go get it right!) RadarOnline has cited Kardashian's fertility struggles and Odom's career issues as the main reasons that the pair has been under enormous strain. According to some speculation, the two are headed for a pricey $67 million divorce.
Katy Perry and John Mayer
John Mayer and Katy Perry may have spent the holidays together but few would argue that their romance, which has already come to a halt twice, is destined to be any more than brief: Mayer's relationships typically don't last long. He dated the likes of Jennifer Love Hewitt, Minka Kelly, Jessica Simpson, and Jennifer Aniston for no more than a year. And Perry is arguably on the rebound from her marriage to Russell Brand, which ended a year ago. Let's hope they both enjoy each other while it lasts!
Kris and Bruce Jenner
For much of 2012, rumors of a split between Kris and Bruce Jenner have been swirling. Over the last few years, their marital rifts have been captured on "Keeping Up With the Kardashians" and it feels like it's only a matter of time before their 21-year marriage comes to an end, as Kris gets more and more wrapped up in the Kardashian "brand." According to the Huffington Post, the two recently sat separately during a Los Angeles Clippers game.
George Clooney and Stacey Kiebler
By now it's clear that Clooney seems to lease hot starlets every few years, so it came as no surprise when the New York Post reported that George Clooney and Stacey Kiebler were on the rocks in October. In recent years he dated Krista Allen, Sarah Larson and Elisabetta Canalis for approximately two years, so it's safe to say his current relationship with Kiebler (which began last fall) will likely come to an end shortly.
The year was filled with high profile celebrity splits -- TomKat, Katy Perry and Russell Brand, and KPatz, for example -- and 2013 is likely to bring several more.
