Tom Cruise & Katie Holmes Every year some of our favorite famous couples decide it isn't working out for them anymore and they break up. Sometimes fans are surprised by the announcement, and other times we wonder why it didn't happen sooner.

One of the most shocking splits was Tom Cruise and Katie Holmes. The actress stunned fans over the summer when she announced her five-year marriage to Cruise was over, and she filed to legally end the union on June 28, citing "irreconcilable differences" for the split.

Katie will receive $400,000 a year in child support for the couple's daughter, Suri. The payments will continue for the next twelve years, totaling $4.8 million by the time Suri turns 18.

Johnny Depp and Vanessa Paradis never married, but they had two children together and spent nearly 15 years as a couple. They reportedly lead separate lives and have been doing so for the past two years. It was also rumored that the actor had an affair with his "The Rum Diary" co-star Amber Heard.

In April, Heidi Klum cited irreconcilable differences for the breakdown of her marriage with Seal. Klum requested joint legal custody of the couple's four kids and primary physical custody. The split turned nasty when Seal accused his former partner of embarking on a romance with the former couple's bodyguard, whom she is currently dating. Klum insists she didn't date her bodyguard while she and Seal were still a couple.

Bradley Cooper was first rumored to be dating actress Zoe Saldana at the end of 2011, when they were spotted ringing in the New Year together with a kiss. Saldana began dating Cooper, her co-star in "The Words," after splitting from her partner of 11 years, fiance Keith Britton. They broke up, and six months later in September the actor's mom reportedly helped them get back together.

After nine years of marriage Amy Poehler and Will Arnett called it quits in September. The pair married in August 2003 and has two children: Archibald William Emerson "Archie" Arnett, 4, and Abel James Arnett in August, 2. Fans were shocked by the split, and no reason was given for the break up.

"New Girl" star Zooey Deschanel and Death Cab for Cutie frontman Ben Gibbard split after two years of marriage. She blamed the split on "irreconcilable differences."

Eva Longoria and her quarterback boyfriend Mark Sanchez split up in October after several months of dating. The actress dated Eduardo Cruz before hooking up with Sanchez over the summer.

"Twilight" star Peter Facinelli and former "Beverly Hills, 90210" actress Jennie Garth split up in March after being married for 11 years. They have three daughters together. Garth and Facinelli issued a statement confirming the divorce news to deny rumors the actor's alleged infidelity was the reason for the split. His new girlfriend, Jaimie Alexander, recently confirmed she was dating Facinelli.

Pop star Avril Lavigne split from Kim Kardashian's half-brother Brody Jenner in January. The reality TV star and pop punk Lavigne began dating since shortly after she split from her husband, Sum 41 rocker Deryck Whibley at the end of 2009. Avril started dating Nickelback rocker Chad Kroeger in July, and the couple became engaged less than eight weeks later.

Did they or didn't they? Selena Gomez and Justin Bieber spurred rumors they split up, possibly due to Bieber's infatuation with Victoria's Secret models. Neither confirmed nor denied reports they broke up. They've since been spotted together numerous times.

Several reports claimed John Mayer called things off with Katy Perry via email after just a couple of months of seeing each other over the summer. They are now reportedly looking to buy a house together.
