Heidi Klum and Seal confirmed late Sunday that they will separate after seven years of marriage. The news comes as a shock to friends and fans alike, as the couple always been considered one of the happiest in Hollywood.
But what went wrong in this seemingly-perfect relationship? Some have speculated that Seal's temper drove the pair apart, while others have said Klum's success -- the supermodel hosts "Project Runway" and recently joined the cast of "Fashion Star" -- might have something to do with the separation.
Research suggests that marriages in which a wife out-earns her husband are more likely to end in divorce -- perhaps because men feel emasculated, or women feel like their husbands are freeloading. News reports have even called this the "alpha wife" phenomenon, arguing that successful women are somehow destroying modern marriages -- though it wouldn't be noteworthy if the opposite were true.
But could this be true for Seal and Klum?
Seal's big hit, "Kiss From a Rose," was released in 1994. And though the singer is set to release a new album, "Soul 2," on Tuesday, Klum has remained in the limelight while Seal hasn't reached the same heights.
Below, five other "alpha wife" star couples who have called it quits.
When Jessica Simpson and Nick Lachey married in October 2002, the two singing stars were on similar career paths. The tide began to turn when Simpson caught the acting bug and starred in "Dukes of Hazzard" in 2005. The couple divorced that year after three years of marriage.
When Avril Lavigne married Sum 41 frontman Derek Whibley in 2006, it seemed to be an indelible pop-punk union. Lavigne's third album reached No. 1 on the charts in 2007, while Sum 41's fifth album, "Underclass Hero," received mixed reviews. After that, the fairytale began to dissolve. After four years of marriage, Lavigne and Whibley divorced in 2010.
"Cruel Intentions" co-stars Reese Witherspoon and Ryan Phillipe seemed like a match made in heaven when they wed in 1999. Shortly afterwards, Witherspoon's film "Legally Blonde," grossed $140 million dollars and she won an Academy Award for "Walk the Line," in 2005. Less than a year after her win, the couple split after seven years together.
Sandra Bullock and Jesse James were not your typical Hollywood couple, but TV's bad boy and Hollywood's golden girl did, however, seem to click. Bullock's career kept on strong regardless of her duties as stepmom and wife to James' three children. She nailed the rom-coms and won an Academy Award for "The Blind Side" in 2010, while James' TV show, "Jesse James is a Dead Man" was cancelled. The couple divorced that year after James' highly publicized infidelities.
Courteney Cox and David Arquette married in 1999 after co-starring in the blockbuster horror film "Scream." The couple also had a daughter together, Coco, in 2004. Making $1 million per episode on "Friends" didn't send Cox into early retirement -- instead she kept going with hit shows like, "Dirt" and "Cougar Town," while her husband's career slowed down. Arquette and Cox split after 11 years of marriage in 2010.
