Relationships come and go as people seek out that special someone to spend the rest of their days with, and Hollywood certainly sees its fair share of unsuccessful tries at love.

The year of 2011 witnessed a number of high-profile marriages, though there were just as many couples who decided that it just wasn't meant to be.

Among the married pairs who sadly parted way during the past twelve months were Jennifer Lopez and Marc Anthony, who now find themselves in a dispute over custody of their shared baby twins, Max and Emme.

Other celebrities divorcing during the year were partners of 72 days, Kim Kardashian and Kris Humphries, along with Ashton Kutcher and Demi Moore, Scarlett Johannson and Ryan Reynolds, Ashlee Simpson and Pete Wentz, Arnold Schwarzenegger and Maria Shriver, and Zooey Deschanel and Ben Gibbard.

Meanwhile, there were a handful of stars who had, fortunately, not yet made it to the altar before deciding to call it quits.

The floundering romance of George Clooney and Elisabetta Canalis made plenty of headlines with Cameron Diaz and Alex Rodriguez, Kate Bosworth and Alexander Skarsgard and Renee Zellweger and Bradley Cooper also among the couples no longer together at year's end.

Rounding out 2011's Tinseltown breakups were Zoe Saldana and fiance Keith Britton, Chaz Bono and Jennifer Elia, Blake Lively and Leonardo DiCaprio, Mila Kunis and Macaulay Culkin, Amanda Seyfried and Ryan Phillippe and Jesse James and Kat Von D, who split not once, but twice over the past twelve months.
