Split In: July 2011

While tabloids had speculated that there was trouble with this couple in 2010, the stars, who are parents to 3-year-old twins Max and Emme, vehemently denied reports and seemed incapable of keeping their hands to themselves while posing together on red carpets. What's more, this A-list couple attended an event together just one week before announcing the split.

The actor-turned-governor made major headlines when the world learned of his affair -- and illegitimate child -- with the family housekeeper, Patty Baena. Shortly after the story broke, the two separated. Shriver moved out of the couple's Southern California mansion and then filed for divorce on July 1, 2011.

Scarlett Johansson and Ryan Reynolds

Split In: 2010

Ryan and Scarlett always kept their relationship on the DL. They didn't talk much of their personal lives, never liked in-your-face PDA, and even tied the knot in secret. But that made the comely couple's breakup after two years of marriage that much more shocking. The supposed cause of the split? Neither was willing to make compromises in their demanding careers so that they could see each other more.

Split In: 2005

They were Hollywood's golden couple for the first half of the 2000s. When they were photographed on a romantic-seeming "double date" vacation together with Courteney Cox and David Arquette, everything seemed hunky-dory. But weeks later, the couple announced the split. Of course, Pitt famously moved on with Angelina Jolie, with whom he'd just filmed the movie "Mr. & Mrs. Smith." They're still together and have six children.

Split In: 2007

Opinions vary about whether the world should have seen this split coming or not, but fans were nonetheless surprised that the couple's eight-year marriage ended so soon after Reese won her first Oscar. The official cause of the split was Ryan's cheating with his "Stop-Loss" co-star Abbie Cornish, but could his infidelity have been spurred on by professional jealousy? Only Ryan (and his shrink) really know.

Split In: 2010

After nearly seven years together, this pairing -- a power couple in both Hollywood and London -- ended. Winslet has not yet finalized her divorce from the acclaimed director. The couple has a son, Joe Alfie, and Mendes had a fatherly relationship with Mia, Winslet's daughter from a previous marriage.

They had a fairytale wedding in France, but Eva and Tony didn't have a happily-ever-after ending. The actress dumped her San Antonio Spurs star hubby of three years when she caught him engaging in extramarital texting with a teammate's wife.

Split In: 2010

Although they're not divorced, these two announced their separation in 2010, after more than 10 years together. Today, they can occasionally still be seen together -- they're still business partners and they even filmed "Scream 4" together -- but there's been no word of a reunion or a full-on split.

Split in: 2008

For over a year, there were whispers that something was amiss in Madonna and Guy's marriage, possibly an affair between Madge and Alex Rodriguez, but the couple adamantly denied that anything was wrong. Two months shy of their eight-year anniversary, they announced their divorce.

Split In: 2010

They were together for nearly five years, but they never married. (McCarthy even said on "Ellen" that she didn't feel they needed a "piece of paper" to make their union official.) Despite seeming happy together -- and a good, goofy match-- the two ultimately went their separate ways.

Split In: 2010

While doing press for her 2010 album, "Bionic," Aguilera gushed about her supportive hubby (and father to their son, Max). But Aguilera's album tanked, and soon after the couple went on a vacation together, the singer filed for divorce. Shortly after the split, she was spotted getting cozy with Matthew Rutler, a set assistant on "Burlesque," which she filmed prior to her divorce.

Split in: 2006

Heather and Richie had been married for 11 years before the "Melrose Place" star decided to call it quits with her rocker husband. But we bet she hadn't envisioned him moving on so quickly -- and with her best friend, Denise Richards, who allegedly encouraged Heather to divorce Richie. Needless to say, that friendship went down the tubes, right along with the marriage.

Split In: 2010

Talk about ties that bind: When Lopez suffered a kidney disease in 2004, his longtime wife gave him one of hers. That made it all the more surprising when the couple divorced -- citing irreconcilable differences -- in 2010, after 17 years together.

Hulk and Linda Hogan

Split in: 2007

Hulk and Linda's split after nearly 24 years of marriage was such a shock that it even took him by surprise. In fact, Hulk learned that Linda had filed for divorce when St. Petersburg Times called him for a comment. Linda quickly began dating  one of her kids' former classmates, 21-year-old Charlie Hill. In December, Hulk got remarried to a woman named Jennifer McDaniel, who is 22 years his junior, and who bears an eerily strong resemblance to his daughter, Brooke.

Split In: 2006

The Armstrong-Crow union seemed like an unlikely -- but happy -- meeting of two major players in their respective fields. But after announcing their engagement in September 2005, the cycling pro and the singer-songwriter split the following February. In an odd twist -- seeing as how Armstrong is a famous cancer survivor -- Crow was diagnosed with breast cancer weeks after the relationship ended.

Split In: 2010

These "Dexter" co-stars, who play siblings on the Showtime series, kept their relationship under wraps for a long time.

The two filed for divorce before their two-year anniversary.

Split In: 2010

After 30 years together, the former vice president and his political activist wife announced their separation. They have not officially divorced, but they remain one of the few longtime political unions to break up not in the wake of a major sex scandal.

Split In: January 2012

We guess Kenny and Lyndie's split was shocking mostly because the smooth jazz saxophonist isn't on our minds very often. Nevertheless, we were thrown for a loop when Lyndie filed for legal separation from Kenny after 20 years of marriage in early 2012. The couple has two sons, Max and Noah, and the divorce battle should be intense: Kenny's worth a reported $50 million!
